Question

in a Pentagon abcde , bc is parallel to de if angle bae is 150° , find angle abc and angle aed if they are in ratio 2:1​

Answer 1

Answer:

a=260° and b= 130°

Step-by-step explanation:

2:1 = 2x+x

2x +x +150° = 540°

2x+x = 540°- 150°

3x = 390°

x = 390°/3

x = 130°

so, a=2x= 2(130°) = 260°

b= x= 130°
