What is the value of y? a. 30 b. 120 c. 60 d. 180

Okay, so we know the first triangle is an equilateral and the second is an isosceles. (the lines indicate congruence)

To find x, we have to figure out the other triangle's angles. 

Since it is equilateral, all its sides are 60 degrees.

All triangles angles add up to 180. 180/3= 60

To find x we subtract the angle beside it by 180 to find the angle's degree. 

180-60= 120. x= 120.

Since it is an isosceles, the last two angles are the same. 
Subtract the vertex from 180. 

180- 120= 60

Divide that by 2. (since there are two angles)

y= 30 Or choice A. 

32

step-by-step explanation:

these are your clues: 1. kim ran 18 races2. this was four fewer races than twice thenumber, notice it says twice the number, so you would do the equation 18x2-4; which equals the number 32.thus, 32 is your answer.
