∠H and ∠I are supplementary angles. If m∠H = 10x + 28 and m∠I = 9x, then what is the measure of ∠H?

Supplementary angles measures 180° , find the value of x to find the measure of ∠H

${ \tt{m∠H + m∠I =180°}}$

${ \tt{(10x + 28 )+ 9x=180°}} \\ { \tt{10x + 9x =180° - 28}} \\ { \tt{19x =152}} \\ { \tt{\frac{19x}{19} = \frac{152}{19} }} \\{ \tt{x =8}}\\ { \tt{∠H =10x + 28 }} \\ { \tt{∠H =10(8)+ 28 }} \\ { \tt{∠H =80 + 28 }} \\ { \boxed{ \green{\tt{∠H =108}}}}$

answer → B. m∠H = 108
