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°

use the power rule  

( a b ) n = a n b n

to distribute the exponent.

apply the product rule to  

3 x 2 y 3 . ( 3 x 2 ) 2 ( y 3 ) 2

apply the product rule to  

3 x 2 . 3 2 ( x 2 ) 2 ( y 3 ) 2

raise  

3

to the power of  

2 . 9 ( x 2 ) 2 ( y 3 ) 2 multiply the exponents in   ( x 2 ) 2

.

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 2 ⋅ 2 ( y 3 ) 2

multiply  

2   by   2 . 9 x 4 ( y 3 ) 2

multiply the exponents in  

( y 3 ) 2 .

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 4 y 3

⋅

2

multiply  

3   by   2 . 9 x 4 y 6
