`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</strong><strong>°</strong><strong> \\ 63 + x + 17 + 4x - 5 = 180</strong><strong>°</strong><strong> \\ 5x + 75 = 180 \\ 5x = 180</strong><strong>°</strong><strong> - 75 \\ 5x = 105</strong><strong>°</strong><strong> \\ x = (105)/(5) = 21</strong><strong>°</strong><strong>`

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 \</strong><strong>\</strong><strong> </strong><strong>angle\</strong><strong>:</strong><strong> </strong><strong>is \: 79</strong><strong>°</strong><strong>`

hope helpful~
