What is the measure of y? (Hint- find the sum of the interior angles first)

Degger [83]

Answer:

Option A. $115\°$

Step-by-step explanation:

we know that

The sum of the interior angles in a polygon is equal to the formula

$S=(n-2)180\°$

where

n is the number of sides of polygon

In this problem we have

$n=5\ sides$

substitute the value in the formula

$S=(5-2)180\°=540\°$

$540\°=90\°+135\°+y\°+88\°+112\°$

Solve for y

$540\°=425\°+y\°$

$y=540\°-425\°=115\°$

Find the average value of the following numbers 87, 79, 84, 70, 90

dem82 [27]

Explanation

the average is calculated by dividing the sum of the values in the set by their number.

Step 1

Let

$\begin{gathered} \text{set}=\lbrace87,79,84,70,90\rbrace \\ the\text{ sum of the values is=87+79+84+70+90}=410 \\ n\text{umber of values= 5} \end{gathered}$

Step 2

apply the equation

$\text{Average}=\text{ }\frac{the\text{ sum of the values}}{\nu mber\text{ of values}}=\frac{410}{5}=82$

so, the answer is 82
