Answer:
Step-by-step explanation:
Given:
Now, from the figure shown below,
The sum of angle efh and angle hfg is equal to the angle efg. This is true because of the angle addition postulate which states that when two angles are formed with the same vertex and different sides, then their sum is equal to the total angle made by both the sides at the vertex.
Here, point 'f' is the vertex and the sides are 'ef and 'fg'.
Therefore,
Plug in their values and solve for 'x'. This gives,
Therefore, the angle measure of each are:
