Answer:

Step-by-step explanation:

I am assuing it is a traingale so the tolal angle is 180

3x+52+x^2+40+70=180

3x+x^2=18

x^2+3x-18=0

(x+6)(x-3)=0

x=-6 x=3

line a x=-6; line b x=3

angle 1:

a. -6*3+52=34

b. 9+52=61

angel 2:

a. -6^2+40=76

b. 9+40=49

Angle 3: 70

a. 70+76+34=180

b. 61+49+70=180
