Ответ:
m∠MHJ = 50°
========================
Step-by-step explanation:
Best explanation is as shown in the attached figure.
As shown in the figure:
x + 15 = 2x - 20 ⇒ vertex angles are congruent
solve for x ⇒ ∴ x = 35°
So, ∠MHJ = 2x - 20 = 2*35 - 20 = 50°
========================================
The measure of all angles will be:
∠MHJ = 2X - 20° = 2 * 35 - 20 = 50°
∠JHK = 180° - ∠MHJ = 180 - 50 = 130°
∠KHL = X + 15° = 35° + 15° = 50°
∠LHM = ∠JHK = 130°
