Question

8
Find the value of x from the given figure: *
(1 Point)
60°
2x
x + 15°​

Answer 1

Answer:

In given figure

∠AOD+∠DOC+∠COB=180

∘

[linear pair]

3x+10+3x+10+2x=180

8x+20=180

8x=180-20

8x=160

x=

8

160

=20

∴ value of x is 20.

Answer 2

Step-by-step explanation:

Given that -: angle A = 60°

and angle B = 2x

and third angle C = x + 15°

as we know that,

the sum of the linear pair angle is 180°

then, angle A + angle B + angle C = 180°

2x + x + 15° + 60° = 180°

3x +75° = 180°

3x = 180° - 75°

3x = 105°

x = 105/3

x = 35°

then angle A = 2×35= 70°

and angle B = 35 + 15 = 50°

and last angle C = 60°

so, 70°,50°,60° are final answer of given question
