find the measure of angle chf.

Hello!

as you can see, ∠AHB is equal to 40°

∠CHF is vertical to ∠AHB

Vertical angles are always congruent, or similar

therefore, ∠CHF = ∠AHB

∠CHF = 40°

I hope this helps, and have a nice day!

∠CHF = 115°

Step-by-step explanation:

∠CHF is a chord - chord angle formed by the chords AC and FB

The measure of the angle is

∠CHF = 0.5( m arc CF + m arc AB, that is

∠CHF = 0.5( 100 + 60 + 30 + 40) = 0.5(230) = 115°
