Question

Angle sum theorem Find the value of x

Answer 1

Answer:

X=62

Step-by-step explanation:

68.5+49.5=118

180-118=62

Answer 2

Answer:

x=62

Step-by-step explanation:

The interior angles of a triangle must add up to 180 degrees.

Therefore, the three angles inside of this triangle should equal 180 degrees when added together.

x+68.5+49.5=180

Combine like terms by adding 68.5 and 49.5

x+(68.5+49.5)=180

x+118=180

We want to find the value of x. Therefore, we must get x by itself.

We should perform the inverse operation to both sides. 118 is being added to x. The inverse of addition is subtraction. Subtract 118 from both sides.

x+118-118=180-118

x=180-118

x=62

x is 62 degrees.
