Question

in figure 4.39 aob is a straight line find the value of x

Answer 1

3x-10+2×+15=180 (linear pair angle )

5×+5=180

5x=180-5

5x=175

x=175/5

35

Answer 2

HLO MATE...

In the figure given , AOB is a straight line( 180 degrees).
we, know AOB= AOC+ COB.

( 3x- 10)+( 2x + 15) = 180 degrees.( linear pair)
5x+ 5= 180
5x= 180- 5
5x= 175
x= 175÷ 5
x= 35 degrees.

So; here x = 35 degrees.
