Question

Q13. In the given figure, lines AB & CD intersect at O. Find the value of:

a) x

b) ∠aoc

c) ∠aod

d) ∠coe​

Answer 1

Answer:

x is 32

Step-by-step explanation:

now put the value of x in the equation and find the angles

Answer 2

Answer:

a) 3x+7+x+5+40°=180°(angles on a straight line)

4x+52=180°

4x=180°-52°

4x=178°

x=128/4

x=32°

b)3x+7+angle aoc=180°(linear pair)

3×32°+7+ angle aoc=180°

96°+7+ angle aoc=180°

103°+angle aoc=180°

angle aoc=180°-103°

angle aoc=77°

c)40°+angle aod=180°(linear pair)

angle aod=180°-40°

angle aod=120°

d)angle coe=3x+7

angle coe=3×32°+7

angle coe=103°
