[tex] \cos(x) = \frac{b}{h} \\ \cos(x) = \frac{4 .9}{6.8} \\ \cos(x) = 0.720 \\ x = \cos^{ - 1} (0.720) \\ x = 44 \degree[/tex]
Answer:
x ≈ 44°
Step-by-step explanation:
We will use a trigonometry function to solve for x. We can see that we have values for the adjacent side and hypotenuse. This means we will be using cosine. Cosine is [tex]\frac{adjacent }{hypotenuse}[/tex]
cos(x) = [tex]\frac{adjacent }{hypotenuse}[/tex] [Given]

Given :-We have given two parallel lines and two lines intersecte each other and act as a transverse Due to the intersection between two parallel and two traverse lines a triangle is formed. The measurements of the given triangle are 60° , 20° and C To Find :-We have to find the values of angles A, B and C Let's Begin :-Here, we have
1 triangle whose measures are 60° , 20° and CTherefore,By using Angle sum property
ASP states that the sum of all angles of triangles are equal to 180°That,
[tex]\bold{\angle{X + }}{\bold{\angle{Y + }}}{\bold{\angle{Z = 180}}}{\degree}[/tex]
Subsitute the required values,
[tex]\sf{ 60{\degree} + 20{\degree} + C = 180{\degree}}[/tex]
[tex]\sf{ 80{\degree} + C = 180{\degree}}[/tex]
[tex]\sf{ C = 180{\degree} - 80{\degree}}[/tex]
[tex]\sf{ C = 100}{\degree}[/tex]
Thus, The value of C is 180°
Now,We have to find the measurement of Angles A and B
Here,
Angle B , unknown angle and Angle C lie on a straight line and we know that the angle formed by straight line is 180°Let the unknown angle be x which is equal to 20° ( Alternative interior angles) Therefore,[tex]\sf{\angle{B + }}{\sf{\angle{ x + }}}{\sf{\angle{C = 180}}}{\degree}[/tex]
[tex]\sf{\angle{ B + 20{\degree}+ 100{\degree} = 180{\degree}}}[/tex]
[tex]\sf{\angle{ B + 20{\degree} = 180{\degree}- 100{\degree}}}[/tex]
[tex]\sf{\angle{ B = 80{\degree} - 20{\degree}}}[/tex]
[tex]\sf{\angle{ B = 60{\degree}}}[/tex]
Now, A, B and 100° lie on a straight line and we know that the angle formed by straight line is equal to 180°Therefore ,[tex]\sf{\sf{A + }}{\sf{\angle{B + }}}{\sf{ 100{\degree} = 180}}{\degree}[/tex]
[tex]\sf{\angle{ A + 60{\degree} = 180{\degree} - 100{\degree}}}[/tex]
[tex]\sf{\angle{ A = 80{\degree} - 60{\degree}}}[/tex]
[tex]\sf{\angle{ A = 20{\degree}}}[/tex]
Hence, The measure of Angles A, B and C are 20° , 60° and 100° .
What is the value of w?
Answers
Answer:
w = 60
Step-by-step explanation:
the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
w + 20 is an exterior angle of the triangle , then
w + 20 = w - 10 + w - 30
w + 20 = 2w - 40 ( subtract w from both sides )
20 = w - 40 ( add 40 to both sides )
60 = w
Answer:
w=60°
Step-by-step explanation:
triangle=180°
angle on a straight line=180°
using that,
we need to find the angle on the same line with that of "w+20°" angle, so we name it as "X"
so, 180-(w+20)=X
expand bracket by multiplying it with the "-"
so it'll be: 180-w-20=X
then rearrange to get like terms together
180-20-w=x
160-w=x
so the missing angle in the triangle is now (160-w)°
now using the angles in a triangle =180°
we add all the angles and equate it to 180, so:
w-30+w-10+160-w=180°
collect like terms again:
w+w-w-30-10+160=180
2w-w+120=180
w+120=180
move 120 to the other side and remember the sign changes, so:
w=180-120
therefore w=60°
now you can substitute w=60 into the triangle and see you'll get 180°

What is probability?Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
The probability that Kabita would take 2 red discs = (number of red discs in bag 1 / total number of discs in bag 1) x (number of red discs in bag 2 / total number of discs in bag 2)

(q+4)(9q+5)=0 solve for q
Answers
Answer:
q = -4
q = -5/9
Step-by-step explanation:
Hi!
To solve this question, we can use the zero product property.
The zero product property states that if one factor is equal to 0, then the whol equation is equal to 0.
We have (q+4)(9q +5) = 0
That means either q + 4 = 0, or 9q + 5 = 0.
Solve:
q + 4 = 0q = -49q + 5 = 09q = -5q = -5/9We can check both cases:
(-4 + 4)(-36 + 5) = 0
0(-31) = 0
0 = 0
(-9/5 + 4)(9(-5/9) + 5) = 0
(2.2)(-5 + 5) = 0
(2.2)0 = 0
0 = 0

Answers
The most reasonable value of n n = -2.
We have given that the length of the football field = 300 feet
It can also be expressed as approximately [tex]5.7\times 10^{n}miles[/tex]
What is the value of one mile in feet?Also, 1 mile = 5280 feet....(1)
We have to find 1 feet so divide both side of equation (1)by by 5280 we get,
[tex]1feet=\frac{1}{5280}[/tex]
Now, for 300 feet is,
[tex]300feet=\frac{1}{5280}(300)[/tex]
[tex]300 feet=0.056818181=0.057miles[/tex]
In scientific notation we have,
[tex]300 feet=5.7\times 10^{-2}miles[/tex]
Therefore we get n = -2.
