Suppose triangle A B C is similar to triangle P Q R. Also, angle A measures 45° and angle B measures 60°.

1 answer:

4 0

Answer: It looks like you are missing the question here. Most of the time in this type of questions, we are looking for the 3rd angle.

Let's assume that you need the 3rd angle.

There are 180 degrees in a triangle. We know 2 of the angles, so by subtracting them from 180 we can find the 3rd angle.

180 - 45 - 60 = 75

Angle C is 75 degrees. In the similar triangle Angle R is also 75 degrees because the corresponding angles are congruent.

Answer: 36 + 4d

Step-by-step explanation:

so basically we just distribute to all the numbers in the parantheses. so 4 times 9 is 36 and 4 times d is 4d.

Answer:

$0.0239\frac{in^{3}}{min}$

Step-by-step explanation:

In order to solve this problem, we must start by drawing a diagram of the cylinder. (See attached picture)

This diagram will help us visualize the problem better.

So we start by determining what data we already know:

Height=6in

Diameter=3.8in

Radius = 1.9 in (because the radius is half the length of the diameter)

The problem also states that the radius will increase on thousandth of an inch every 3 minutes. We can find the velocity at which the radius is increasing with this data:

$r'=\frac{1/1000in}{3min}$

which yields:

$r'=\frac{1}{3000}\frac{in}{min}$

with this information we can start solving the problem.

First, the problem wants us to know how fast the volume is increasing, so in order to find that we need to start with the volume formula for a cylinder, which is:

$V=\pi r^{2}h$
