Question

question if m∠fhc = 73°, then what is m∠fhd?

Explanation:

Step1: Note angle - relationship

$\angle FHC$ and $\angle FHD$ are a linear - pair.

Step2: Use linear - pair property

The sum of angles in a linear - pair is $180^{\circ}$. So $m\angle FHD=180^{\circ}-m\angle FHC$.

Step3: Substitute given value

$m\angle FHD = 180 - 73=107^{\circ}$.

Answer:

$107^{\circ}$
