Answer:
The measure of EHG = 120°
Step-by-step explanation:
There are three vectors originating from point H and joining three points E, F and G.
The given angles between vector HG and HF is 30° and between vector HE = 90°
Therefore, Angle between vector HE and HG = angle between HE and HF + angle between HF and HG.
∠ EHG = ∠ EHF + ∠ FHG
= 90° + 30°
= 120°
The measure of EHG = 120°
