Answer 1

Answer:

Let the common factor be k.

So 3k + 4k + 90 = 180

9k + 90 = 180

k + 10 = 20

k = 10

a = 30, b = 50

Now if RS is a line, then,

a + c = 180

30 + c = 180

c = 150

Hope it helps

Answer 2

Answer:

c= 120°

Step-by-step explanation:

Given, PQ perpendicular to AB

and a:b=4:5 can be written as

a/b =4/5

5a = 4b

a= 4b/5 and a+b = 90

(4b/5)+b=90

9b/5=90

b/5=10

b=50

automatically a = 40

If RS is straight line the a+c = 180

c= 180- 40

c= 120°

This is required answer.
