Question

What is the value of y? Show work

Answer 1

Answer:

Sum of the angles of the triangle is 180°.

=> 39° + 4y + y + 11° = 180°

=> 5y + 50° = 180°

=> 5y = 180° - 50°

=> 5y = 130°

=> y = 130°/5

=> y = 26°

Answer 2

Answer:

Sum of the interior angles of the triangle is 180°.

According to the above problem,

$4y + (y + 11) + 39 = 180 \\ 5y + 50 = 180 \\ 5y = 130 \\ y = \frac{130}{5} \\ \boxed{y = 26}✓$

y=26° is the right answer.
