Question

What is the value for y? Explain how you arrived at your answer.

Answer 1

`y = 14`

Explanation:

The sum of internal angles in a triangle is `180^@` The considered triangle is an isosceles triangle `bar(AC)=bar(BC)` so `50 =2x->x = 25`

Considering the whole triangle we have

`180 = 2 cdot 50 + 5y+10->y = 14` so finally

`x = 25` and `y = 14`
