Question

Find the value of x in the triangle shown below.

Answer 1

48 degrees

Explanation:

Since the triangle is iscoceles because it has two sides with a length of 7, two angles will be 66 degrees and the missing angle will be the sum of total angles in a triangle minus the other two 66 degree angles. 180 - 66 - 66 = 48

Answer 2

x=48

Explanation:

The other angle is 66° because it's an isosceles triangle

so

180=66+66+x

180=132+x

x=48
