Question

Can somebody please help me answer this question ?

Answer 1

x = 8.5

Explanation:

Because of the geometric property of triangles... we know that the two triangles are congruent.

Angle A = Angle E

and Angle B = Angle D

Therefore... If we find the angle of B, we also find the angle of D (because they're the same)

Since the sum of interior angles of a triangle is 180°... just subtract the two angles already given (50° + 45° = 95°) from the total 180° to find the last angle.

When you do that... you find that Angle D = 85°

Divide 85 by 10 to solve for x

x = 8.5

Answer 2

x=5

angle a is = to angle d
