Question

i do not know this ans

Answer 1

Answer:

your answer is

given that,,,

P:Q:R= 2:3:4

as we know straight line denotes 180°

hence angle P + angle Q+ angle R =180°

let,,,,,

angle p be 2x...........(1)

angle q be 3x ...........(2)

angle r be 4x ...........(3)

2x+3x+4x=180°

9x=180°

x= 20°

hence,,,,,by (1) , (2), (3)

p= 40°

q=60°

r=80°

hope it helped

Answer 2

Answer:

P : Q : R = 2 : 3 : 4

Let, P = 2x

Q = 3x

R = 4x

P + Q + R = 180° (Linear pair)

2x + 3x + 4x = 180°

9x = 180°

x = 180°/9

x = 20°

So,

P => 2x = 2×20 = 40°

Q => 3x = 3×20 = 60°

R => 4x = 4×20 = 80°
