Find the missing angle in a triangle with the given sides.

Answers

Answer 1

Answer:

[tex] \angle[/tex]Z = 1°

Step-by-step explanation:

Since the shape is a triangle it means that all it's interior angles sum to 180°

To find the missing angle sum up the known angles and subtract them from 180°

That's

[tex] \angle[/tex]X + [tex] \angle[/tex]Y + [tex] \angle[/tex] Z = 180°

89° + 90° + [tex] \angle[/tex]Z = 180°

[tex] \angle[/tex]Z = 180 - 179°

We have the final answer as

[tex] \angle[/tex]Z = 1°

Hope this helps you

Answer 2

Answer:

1°

Step-by-step explanation:

Given angles

<x=89°<y=90°

We know that in a triangle

Sum of angles=180°

[tex]\rm \mapsto \angle x + \angle y + \angle z = 180 \\ \rm \mapsto89 + 90 + \angle z = 180 \\ \rm \mapsto179 + \angle z = 180 \\ \rm \mapsto\angle z = 180 - 179 = 1[/tex]

The first 2 on top is not a function. The 3rd one on top and the bottom 2 are functions.

Step-by-step explanation:

The x-value cannot have more than 1 y-value or else when you plot the points on the graph, it doesn't meet the vertical line test. The vertical line test indicates whether or not the graph is a function. Different x-values can have the same y-value.

Function examples: (3,-4), (5,0), (0,-4), (1,2)

Not a Function examples: (0,8), (2,-1), (0,-2), (-5,3)

Phil and his family want to do something fun and memorable on Leap Day. They each come up with an activity: attend a trapeze class, go fishing, go on a hike, or visit a theme park. They settle on picking the letters L, E, A, and P from a bowl, replacing them after each pick, to make the decision. They repeat this experiment 40 times to verify their model and record the results in this table.
Below is the chart
Activity Letter Times Picked
trapeze class L
10
fishing E
11
hiking A
9
theme park P
10

Based on the results in the table, is this model a fair representation for choosing an activity?
A.
No, it is an unfair model because the outcomes have different frequencies.
B.
No, it is an unfair model because the relative frequency of the letter E is the highest.
C.
Yes, it is a fair model because the relative frequencies of the letters L and P are equal.
D.
Yes, it is a fair model because the relative frequencies of all the outcomes are similar.

Answer: number 2 is they will each get 3/8 of a pizza

Step-by-step explanation:

this is because if you draw out a circle and take out 1/4 out of it there is 3/4ths left. by knowing this you can see that 3/4ths is not equal for the 2 friends. so for it to be equal we reverse simplify to then make it 6/8ths. there we go, and even number. now we half the 6/8ths to then make it 3/8ths of the pizza for each person.

Answer:

(question 2) 3/8

(question 3.) 16 servings

Step-by-step explanation:

(question 2) 3/4 divided by 2 = (3/4)(1/2)=3/8

(question 3) 6/1 divided by 3/8 = (6/1)(8/3)= 48/3 = 16
