Question

Find the unknown marked angles in each of the following figures...plz give answer in step by step answer with explanation plz ....

Answer 1

You can draw a perpendicular line from D down AB.

Now, ΔADH will form. It is right-angled at ∠H.

Sum of all angles of a triangle is 180°

∠D + 63° + 90° = 180°

∴∠D is 27°

x = ∠D + 90°

Therefore, x=117°.

x=y

y=117°
