Question

The sum of the measures of angle ONE and angle TWO is 180°.
The measure of angle ONE is 7x.°.
The measure of angle TWO is 55°.
What is the value of x?

Answer 1

The sum of the measures of angle ONE and angle TWO is 180°, so we can write the equation:

7x + 55 = 180

Subtracting 55 from both sides, we get:

7x = 180 - 55
7x = 125

Dividing both sides by 7:

x = 125/7
x ≈ 17.86
