Question

In figure 3.38, AOC is a line, find x.​

Answer 1

given,

AOC is a line.

if angle AOB = 70°, angle BOC = 2x

find x.

Since AOC is a straight line, the angles will add up to 180°

hence, angle AOB+BOC = 180°

70°+2x = 180°

2x = 180°-70°

2x = 110°

x =

$\frac{110}{2}$

x = 55°.

hope it helps

thanks!!

Answer 2

Answer:

hello,

Step-by-step explanation:

from the figure,

70°+2x=180°

2x=180°-70°

2x=110°

x=110/2

x=55°

hence,x=55°

hope it helps you
