Answer:
#11-13: 118 , 97 , 62
#7-10: 92 , 125 , 56 , 130
Step-by-step explanation:
#11. Supplementary angles (A + B = 180)
(n + 7) + (3n - 47) = 180 n = 55 <ABC = 3(55) - 47 = 118 degrees #12. Supplementary angles
83 + x = 180 x = 97 <ABC = 97 degrees #13. Congruent angles (A = B)
(8x - 34) = (5x +2) x = 12 <DEF = 5 (12) + 2 = 62 degrees #7. Congruent angles
(3x +23) = 4x x = 23 <ABC = 4(23) = 92 degrees #8. Congruent angles
5x = (3x + 50) x = 25 <MPQ = 3(25) + 50 = 125 degrees #9. Congruent angles
(a + 28) = 2a a = 28 <MNP = (28) + 28 = 56 degrees #10. Congruent angles
5y = (2y + 78) y = 26 <WXZ = 5(26) = 130 degrees
I hope this helps!
