Question

What is m∠G ?

Answer 1

`m /_G = color(blue)(121^circ)`

Explanation:

The sum of the interior angles of a triangle is always `180^circ`

Therefore
`color(white)("XXX")x+(x-5)+(3x+25)=180`

`color(white)("XXX")rarr 5x+20=180`

`color(white)("XXX")rarr 5x=160`

`color(white)("XXX")rarr x=32`

SInce `m/_G` is given as `(3x+25)^circ`

`color(white)("XXX")m/_G=(3 * (32)+25)^circ=(96+25)^circ=121^circ`
