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:
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.
