Answer:

A= 58 degrees B=25 degrees

Step-by-step explanation:

A+B=83

(9x+4) + (4x+1)=83

x=6

Solve for angles

Answer:

angel A = 25°

angel B = 58°

Step-by-step explanation:

ACD + ACB = 180°

83° + ACB = 180°

ACB = 180° - 83°

ACB = 97°

ACB + angel B + angel A = 180°

97° + 4x + 1° + 9x + 4° = 180°

13x = 180° - 102°

13x = 78°

x = 78°/13

x = 6

angel A = 4x + 1°

angel A = 4(6) + 1°

angel A = 24 + 1°

angel A = 25°

angel B = 9x + 4°

angel B = 9(6) + 4°

angel B = 54 + 4°

angel B = 58°
