In the figure described, since the two triangles form a straight line, the sum of the angles at the vertex where they meet must be 180 degrees.
Therefore, we can calculate the measure of angle x as:
x + 55 + 55 = 180
x + 110 = 180
x = 70
So, the measure of angle x is 70 degrees.
Therefore, the answer is 70°.
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°
