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.
