HELP ME PLS bro i suck at math;-;

Answer 1

$\huge\underline\color{pink}{Answer ☘}$

$angle \: sum \: property \: of \: a \: triangle \\ states \: that \: the \: sum \: of \\ all \: the \: three \: angles \: of \: a \: triangle \: is \\ equal \: to \: 180°$

therefore~

$63 + (x + 17) + (4x - 5) = 180° \\ 63 + x + 17 + 4x - 5 = 180° \\ 5x + 75 = 180 \\ 5x = 180° - 75 \\ 5x = 105° \\ x = \frac{105}{5} = 21°$

therefore the measure of all the angles are..

∠1 = 63°

∠2 = ( x + 17 ) = ( 21 + 17 ) = 38°

∠3 = ( 4x - 5 ) = ( 84 - 5 ) = 79°

$thus \: the \: measure \: of \: the \: largest \\ angle\: is \: 79°$

hope helpful~
