Since the angles at the base are each 55 degrees, the total angle at the base of the lower triangle is 55 + 55 = 110 degrees.
Since the two triangles form a straight line, the sum of all the angles must be 180 degrees. Therefore, x + 110 = 180.
Solving for x:
x = 180 - 110
x = 70
Therefore, the measure of angle x is 70 degrees. So, 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.
