This right angle was measured at 10 times whatever x is.

If I wanted to solve for x, what would be a good equation to figure that out?

10 + 90 = x

10x = 90

x - 9 = 100

9x = 10

This right angle can be expressed by the equation:


10x = 90


Solve for x.

x = 1

x = 9

x = 90

x = 10

This right angle has the angle 2y + 70. If I wanted to figure out what y is equal to, what equation would I use?

70 = 90

2y = 90

2y + 70 = 90

2y + 70 = 100

This right angle has the angle 2y + 70. So I can use the equation


2y + 70 = 90


Solve for y.

y = 80

y = 90

y = 70

y = 10

These two angles are complementary (they combine to be a right angle).


One angle has a measurement of x. The other angle is exactly 4 times larger (4x).


What equation could we use to solve for x?

4x + x = 90 .... or just 5x = 90

4x = x

90 + 4x = x

x = 90
