Question

Find the value of
�
xx in the triangle shown below.

Answer 1

108

Explanation:

Sum of angles in triangle = 180

So 45 + 27 + x = 180

X = 180 - 45 - 27

X = 108

Answer 2

• x = 108°

Explanation:

The three angles in a triangle always add up to 180°, ,meaning:-

• x+27+45=180°

Missing angle is 180 minus the measures of the other two angles:

• x=180-45-27x

• x = 108
