Question

7) In the given figure, find the value
of Xi
D
IC
(x+20)
(x+3)(x+7)
B
40°
O 50°
60°
O 80​

Answer 1

Answer:

these 3 angles are linear pair and sum of 3 angles is 180

Step-by-step explanation:

x+3+x+20+x+7=180

3x+30=180

3x=180-30

3x=150

x=150/3

x=50

Answer 2

Answer:

x + 3 + x + 20 + x + 7 = 180°.... ( linear pair )

3x + 30 = 180 °

3x = 180 - 30

3x = 150°

x = 150/3

X = 50°

now

X+ 3 = 53

X + 20 = 70

X + 7 = 57

hope it helps
