Question

What is the value of y?114Answer:

Answer 1

Y = 57
because is the remaining angle is (180-114) then 2y = 114
2y = 114 : divide it by 2
y = 57

Answer 2

Answer:

value of y is, $57^{\circ}$

Step-by-step explanation:

Exterior angle property of a triangle says that:

Sum of the two opposite interior angles.

From the given triangle:

Sum of two  opposite interior angles = y +y = 2y

Since, 114 degree is an exterior angle of a triangle,

By Exterior angle property of a triangle :

$2y = 114$

Divide both sides by 2 we have;

y = 57 degree

Therefore, the value of y is, $57^{\circ}$
