Answer:

Step-by-step explanation:

OA=OB=OC

∠A = ∠1

∠B = ∠2

∠A + ∠B + ∠C = 180°

∠A + ∠B + (∠1 + ∠2) = 180°

∠1 + ∠2 +  (∠1 + ∠2) = 180°  ... subtitution

2 x (∠1 + ∠2) = 180°

∠1 + ∠2 = 90°

∠ACB = 90°

Someone please help me out I rlly need help
Anit [1.1K]

The equation that could be used to solve for x is (3x-1) = 140 and the value of x is 47°.

According to the question,

We have the following information:

We have two lines that are intersecting each other at a point. The angles made on this point are given.

Now, we know that these two angles are vertically opposite angles. And we also know that vertically opposite angles are equal.

So, we will have the following equation:

3x-1 = 140

Now, we can easily find the value of x from this equation:

Adding 1 on both sides of the equation:

3x = 140+1

3x = 141

Dividing by 3 on both sides:

x = 141/3

x = 47°

Hence, the equation that could be used to solve for x is (3x-1) = 140 and the value of x is 47°.
