Question

angle AOC and angle BOC form linear pair. AOC =5x+7 BOC =x-1 find x
​

Answer 1

Given

Angle Aoc and Boc forms a linea pair.

Hence,

Angle AOC + BOC = 180.

Now,

Angle AOC = 5x+7

Angle BOC = x-1

so,

5x + 7 + x - 1 =180

6X+6 = 180

6x = 180 -6

6x = 174

x = 174 / 6

x = 24

So angle AOC = 5X +7

= 5 ×24 +7

= 127°

AND ANGLE BOC = X-1

= 24-1 => 23°

Answer

AOC = 127°

BOC = 23°

Answer 2

• AOC+BOC=180. { L.P}
• 5X + 7 +X-1=180
• 6x+6=180
• x=174/6
• x=29

• AOC=5x+7
• =5×29+7
• =152

• BOC=x-1
• = 29-1
• =28

• angle AOC=152

• angle BOC=28
