The red arrows show that the lines are parallel, but using the stuff given you can make an equation.
its hard to explain without drawing but starting from the 60 if you can make a Z you will get alternate angles and that mean that the given equation MUST be equal to 60. So,

8x-4=60

8x=60+4

8x=64

x=64/8

x=8 (is your answer)

hope you understand

Find the range of f

Ugo [173]

Write down y=f(x) and then solve the equation for x, giving something of the form x=g(y).
Find the domain of g(y), and this will be the range of f(x). ...
If you can't seem to solve for x, then try graphing the function to find the range.

Let ∠Q be an acute angle such that tanQ=0.04. Use a calculator to approximate the measure of ∠Q to the nearest tenth of a degree

Digiron [165]

We have been given that ∠Q is an acute angle such that $\text{tan}(Q)=0.04$ . We are asked to find the measure of angle Q to nearest tenth of a degree.

We will use arctan to solve for measure of angle Q as:

$Q=\text{tan}^{-1}(0.04)$

Now we will use calculator to solve for Q as:

$Q=2.290610042639^{\circ}$

Upon rounding to nearest tenth of degree, we will get:

$Q=2.3^{\circ}$

Therefore, measure of angle Q is approximately 2.3 degrees.

8. Don made deposits of $500 at the end of each year for eight years. The rate is 8% compounded annually. Using the tables found

Sonbull [250]

Answer:

Step-by-step explanation:

P = $ 500 ;r =8% ; n= 8

A = P* (1+r/100)^n

A= 500 * ( 1 + 8/100)⁸

= 500 * ( 1 + 0.08)⁸ = 500 * 1.08⁸

=500*1.85

= $ 925.45

A kite flying in the air has a 12 - ft line attached to it. its line is pulled taut and casts a 10 - ft shadow. find the height

tekilochka [14]

The height of the kite will be 6.6 ft rounded to the nearest tenth.

<u><em>Explanation</em></u>

According to the below diagram, AB is the height of the kite and AC is the 12 ft line attached to it.

The line is pulled taut and casts a 10 ft shadow. That means BC = 10 ft

Now, in right angle triangle ABC, using <u>Pythagorean theorem</u>....

$(AB)^2 +(BC)^2 = (AC)^2 \\ \\ (AB)^2 +(10)^2 = (12)^2 \\ \\ (AB)^2 +100 = 144\\ \\ (AB)^2 = 144-100 =44\\ \\ AB=\sqrt{44}= 6.6332....$

So, the height of the kite will be 6.6 ft rounded to the nearest tenth.
