What is the value of x? answers: A) 90° B) 65° C) 50° D) 80°

The measure of angle 'x' is 65 degrees and this can be determined by using the properties of the isosceles triangle.

Given :

Angles  ---   and x

The following steps can be used in order to determine the measure of angle 'x':

Step 1 - Both the triangles are isosceles triangles because in both the triangles two sides are similar.

Step 2 - Let the upper triangle be ABC and the lower triangle be DBE.

Step 3 - The angle B of the triangles can be calculated as:

Step 4 - Now, angle 'x' can be calculated as:

The measure of angle 'x' is 65 degrees. Therefore, the correct option is B).

x = 80°

Step-by-step explanation:

These are both isosceles triangles, so the top 2 angles are both 65°. The last angle of that triangle is 180° - (65° + 65°) which is 50°. Then, the opposite of that angle is in the next traingle. It is also 50°. So the 2 base angles are both 50°, so x is 180° - (50° + 50°) which is 80°.
