Question

Find the measure of angle x in the figure below:

Two triangles are shown such that one triangle is inverted and share a common vertex. The lower triangle has two angles at the base marked as 55 degrees each. The angle at the vertex of the inverted triangle at the top is marked as x degrees.
65° 70° 110° 125°

Answer 1

angle x is 70° angles in a tuangle add up to 180. so 55+55=110. 180-110=70 and 70 and x are opposite so they are opposite angles

Answer 2

70 degrees

Explanation:

Because an area of a triangle is 180.

55 + 55 = 110 180 - 110 = 70

110 + 70 = 180
