Question

What is the value of y?

Answer 1

The answer is C.

Step-by-step explanation:

Given that total angles in a triangle is 180°. In order to find the value of y, you have to add up all the angles in terms of y and make it equals to 180°:

`y + y - 12 + 56 = 180`

`2y + 44 = 180`

`2y = 180 - 44`

`2y = 136`

`y = 136 / 2`

`y = 68`
