Question

P.
X
7x+30°
Q
2x
R
Find out the value of c

Answer 1

Step-by-step explanation:

we know that some of all angels of triangle is 180°

so X+7x+30+2x=180

→ 10x+30=180

→10x=180-30

→ 10x=150

→x=15

so all angles are 15°,135°&30

Answer 2

Answer:

Over here x is 15

Step-by-step explanation:

umm i can't see any c which u r asking abt

ig it's a typing mistake

so to find the value of x -

p + q +r = 180 degree

x + 7x + 30 + 2x = 180 degree

8x + 2x = 180 - 30

10x = 150 degree

x = 150 / 10

x= 15

i hope , this Will help u
