Question

Find the value of x in the following figures​

Answer 1

Answer:

Angles on one side of a straight line always add to 180°.

So,

=> (x+30)°+(115-x)°+x° = 180°

=> x° = 180°-115°-30°

=> x° = 35°

Answer 2

Answer:

value of x is 8

Step-by-step explanation:

angle AOC= 90°

AOC = AOB +BOC

90°=40°+BOC

90-40=BOC

50°=BOC

(6x+2)=BOC

(6x+2)=50°

6x=50-2

6x=48

x=48/6

x=8
