Mathematics
1 answer:
Fantom [35]3 years ago

Answer:

∠2 = 51°

Step-by-step explanation:

The sum of supplementary angles = 180°

Equate the sum of the angles to 180 and solve for a

11a + 19 + 6a - 9 = 180

17a + 10 = 180 ( subtract 10 from both sides )

17a = 170 ( divide both sides by 17 )

a = 10

Hence

∠2 = (6 × 10) - 9 = 60 - 9 = 51°
