Question

Question 1
Tell whether the angles are complementary or supplementary. Then find the value of x.
The angle is complementary but I don't know the value of x.
the angles are
x and (x-20)

Answer 1

Answer:

55

Step-by-step explanation:

If they're complementary, that means they add up to 90 so:

x + x - 20 = 90

Then, solve.

$2x - 20 = 90\\2x = 110\\x= 55$
