Question

Can i get help on 23?

Answer 1

ngle A=77

Angle B=103

Explanation:

∠A+∠B=180 ( supplementary angles)

3/8 x +50+x+31=180

3/8 x+x=180-81

11/8 x=99

11x=99*8

x=(99*8)/11 =72

Angle A= 3/8 (72)+50

Angle A=27+50=77

Angle B= 72+31=103

Answer 2

m<a = 77

m<b= 103

Explanation:

m<a+m<b = 180(supplementary angles)

3x/8+50+x+31=180

3x/8+x+81=180

(3x+8x)/8=180-81

3x+8x=99*8

11x=792

x=792/11

x=72

now

m<a=3x/8+50

=(3*72)/8+50

=77

m<b=x+31

=72+31

=103
