Answer
76$^\circ$, 61$^\circ$, 43$^\circ$
Work Step by Step
The sum of the measures of the angles in a triangle is always 180$^\circ$.
4x+3x+4+2x+5=180
(4x+3x+2x)+(4+5)=180
(7x+2x)+9=180
9x+9=180
9x=180-9
9x=171
x=$\frac{171}{9}$
x=19
4x=4(19)=76$^\circ$
3x+4=3(19)+4=57+4=61$^\circ$
2x+5=2(19)+5=38+5=43$^\circ$
