I Need The Answer Plz!!! Geometry Is Hard!!!

Mathematics
1 answer:
Scorpion4ik [409]2 years ago

Answer:

B. 10

Step-by-step explanation:

First, we need to recognize that the two triangles are similar (the triangle with a leg value of 21 and the triangle with a leg value of 4 and hypotenuse x)

Let's first label the leg of the second triangle as y.

Then, we can set up this equation

\frac{21}{y} =\frac{y}{4}

Cross multiplying gives us

84=y^2

So, y=sqrt(84) or 2 sqrt(21).

Now, using the pythagorean theorem, we get

4^2+2sqrt(21)^2=x^2

100=x^2

x=10

Answer:

24.27 cm

Step-by-step explanation:

sin 65 degrees = 22/x, so:

------------------ = ------

 sin 65 deg       22

so x = 22 / (sin 65 deg) = 22/0.906 = 24.27 cm

Can someone help me out on this problem and show work
DochEvi [55]

Answer: 4230.14

Step-by-step explanation:

The amount that the balance is multiplied by each month is

\frac{2448}{2040}=1.2.

So, after t months, the balance is 1700(1.2)^{t-1}.

Substituting in t=6, we get the balance is

1700(1.2)^{6-1}=\boxed{4230.14}, to the nearest hundredth.
