Answer:

\huge\boxed{\sf d = 141\ feet}

Step-by-step explanation:

<u>Given Data:</u>

Circumference = C = 443 ft

<u>Required:</u>

Diameter = d = ?

<u>Formula:</u>

d = C / π

<u>Solution:</u>

d = 443 / 3.14

d = 141.0 feet

d = 141 feet

EleoNora [17]
We want to find 9.5% of $50.

First put 9.5% in decimal form. 9.5% = 0.095.

Then multiply 0.095 by 50. 50 * 0.095 = $4.75 fee

The money Kennedy will recieve is going to be 50 dollars minus the $4.75 fee.

50 - 4.75 = $45.25 with the fee subtracted

Can someone please answer. There is one problem. There's s picture. Thank you!

The correct answer is the first option, 23.1 miles.

Knowing that the sum of the triangle's interior angles should equal a measure of 180°, you can start off by solving for the missing interior angle, near the library.

Since this is a right triangle (meaning one of the angles is 90°), and the other angle is given (57°), simply subtract these two values from 180° to get 180-(57+90)=33\textdegree.

Next, use the Law of Sines (stated below) which will allow you to solve for the missing distance from the radio tower to the library in miles, using the angle measures and height from the tower to the balloon that you've found.

\frac{\sin(A)}{a} =  \frac{\sin(B)}{b}

For this problem, we'll let the height of the hot air balloon be a=15 and its respective opposite angle be A=33\textdegree, and let the missing x-distance be b, with its respective opposite angle B=57\textdegree. Note, we're solving for b.

\frac{\sin(33)}{15} =  \frac{\sin(57)}{b} \\ \\&#10;b\times sin(33)=15\times \sin(57) \\ \\&#10;b=\frac{15\times \sin(57)}{sin(33)} \\ \\&#10;b\approx \frac{15\times 0.84}{.54} \\ \\&#10;b\approx \frac{12.6}{.54} \\ \\&#10;b\approx \frac{12.6}{.54} \\ \\&#10;b\approx 23.3

Because there was a lot of approximation in the above operations, the answer doesn't exactly match any of the answer options in the question. However, it's very close to the first option, 23.1 miles, so that must be the correct answer.

What is the measure of the<br> third angle of this triangle?
Illusion [34]

Answer:

20 degrees

Step-by-step explanation:

every triangle had 3 angles that all add up to 180

the problem gives you two angles which are 120+40 which is 160

180-160 is 20 degrees which is whi it is the answer
