Solve the following equation: 8 - 9x = 27.
bearhunter [10]

The given equation is

8-9x=27

To solve for x, we have to subtract 8 to both sides

8-9x-9 = 27-8 \\ -9x = 19

Now we need to get rid of -9 from the left side, and for that we do division

\frac{-9x}{-9} = \frac{19}{-9}

x = - \frac{19}{9}

The sum of the measures of two adjacent angles is 72 degrees. The ratio of the smaller angle to the
Goryan [66]

Answer:

The larger angle is 54°

Step-by-step explanation:

Given

Let the angles be: θ and α where

θ > α

Sum = 72

α : θ = 1 : 3

Required

Determine the larger angle

First, we get the proportion of the larger angle (from the ratio)

The sum of the ratio is 1 + 3 = 4

So, the proportion of the larger angle is ¾.

Its value is then calculated as:.

θ = Proportion * Sum

θ = ¾ * 72°

θ = 3 * 18°

θ = 54°
