Question

< A and < B from a linear pair < A = 5a + 16 and < B = 144°, find a and the measure of angle A​

Answer 1

Answer:

a= 4 , ∠A = 36°

Step-by-step explanation:

Linear pair means their Sum is 180°

So ∠A + ∠B = 180°

5a + 16 + 144 = 180

5a + 160 = 180

5a = 180 - 160

5a = 20

a = (20/5)

a= 4

If a = 4 , ∠A = 5a + 16  

= 5(4) + 16

= 20 +1 6

36
