Step-by-step explanation:

Let alpha be the unknown angle. We can set up our sine law as follows:

$\frac{ \sin( \alpha ) }{5 \: m} = \frac{ \sin(42) }{3.6 \: m }$

$\sin( \alpha ) = \frac{5 \: m}{3.6 \: m} \times \sin(42) = 0.929$

Solving for alpha,

$\alpha = arcsin(0.929) = 68 \: degrees$

An antenna is atop the roof of a 100 foot building, 10 feet from the the edge, as shown in the figure below. From a point 50 fee

Brut [27]

I think it must be the right triangle so
x=height of the antenna
tan(66)=x/50
x=50*tan(66)
x=1.33 ft
->the height of the antenna = 1.33 ft
hope it is the correct answer because you didn't provided me enough information.

Dominick ate 1/ 4 of an 8 slice pizza how many slices did he eat.

lana66690 [7]

2 slices

If you take the 1/4, and the 8 (which can be re written as 8/1), and multiply them together, you get two.

1/4*8/1=2

Andre wants to buy a bike that has a price tag of $125. What was the wholesale cost of this bike?

san4es73 [151]

The bike store marks up the wholesale cost of all of the bikes they sell by 30%. Andre wants to buy a bike that has a price tag of $125. What was the wholesale cost of this bike?

Answer:

$96.15

Step-by-step explanation:

Let x be the wholesale cost of the bike.

Given:

Price tag of a bike = $125.

The bike store marks up the wholesale cost of all of the bikes they sell by 30%.

So we can find the wholesale cost of the bike by the following way.

$\frac{100+30}{100}\times x = 125$
