Solve the equation -88=2+2(5m-5)

const2013 [10]

-88 = 2 + 2(5m - 5)

Distribute 2 inside the parentheses.

-88 = 2 + 10m - 10

Combine like terms on the right side.

-88 = -8 + 10m

Add 8 to both sides.

-80 = 10m

Divide both sides by 10.

$\boxed {m = -8}$

A wall with a height of 20 feet is braced with a support post that forms a 30 degree angle with the top of the wall. What is the

dexar [7]

The length of the support post is 40 ft.

Solution:

Given, the height of the wall is 20 ft; support post forms 30 degree

Refer the attached image

Let us name the triangle as ABC where AB is the wall (opposite side) of 20 ft and $\angle A$ is 30 degree ( $\theta$ ) and AC is the length of the post.

To find: The length of the post (AC)

we know the formula, $sin\theta=\frac{opp}{hyp}$ (trigonometric formula)

On substituting the values we get,

$\Rightarrow sin(30^{\circ})=\frac{20}{AC}$

The value of sin 30 degree is 0.5

$\Rightarrow 0.5=\frac{20}{AC}\rightarrow AC=\frac{20}{0.5}\rightarrow AC=40 ft$
