Question

The angles of quadrilateral are in the ratio 4:5:10:11. The angles are:
a. 36°, 60°, 108°, 156°
b. 48°, 60°, 120°, 132°
c. 52°, 60°, 122°, 126°
d. 60°, 60°, 120°, 120°​

Answer 1

Answer:

Answer: (c)

Explanation: Let x be the common angle among all the four angles of quadrilateral.

As per angle sum property, we know:

4x+5x+10x+11x = 360°

30x = 360°

x = 12°

Hence, angles are

4x = 4 (12) = 48°

5x = 5 (12) = 60°

10x = 10 (12) = 120°

11x = 11 (12) = 132°

Answer 2

Answer:

4+5+10+11=30

360/30=12

4×12=48

5×12=60

10×12=120

11×12=132

option b is correct
