Answer:
100°
Step-by-step explanation:
Ok so it looks overwhelming at first, but you just need to make sections and break it down
You are looking for h°, so you want to make it a triangle
The angles of this triangle would be h°, 40°, and x°
You can find x° by using the 140° on the same line
it is a straight line, so that means its angle is 180°
180° - 140° = 40°
x° = 40 °
so now you know that the angles in the triangle are h°, 40°, and 40°
Every triangle has angles that measure to 180°
180° - 40° - 40° = 100°
h° = 100°
