Question

Tell whether the angles are complementary or supplementary. Then find the value of x

Answer 1

Answer:

Complementary, x=60.

Step-by-step explanation:

The angles are complementary because they add up to 90 degrees, opposing supplementary angles, which add up to 180 degrees. To find x, we need to form an equation to represent the problem. We know the two angles add up to 90 degrees, so we can use that to make the equation.

(x-30)+x=90  Simplify.

x-30+x=90

2x-30=90      Add 30 to both sides.

  +30 +30

2x=120          Divide both sides by 2.

x=60

We can also find the value of the angles by plugging in x.

Angle 1: (x-30)

             (60-30)

             30 degrees

Angle 2: x

              60 degrees

(You can also notice that the two angles add up to 90 degrees, which is another way of telling that the angles are complementary.)
