<h3>Answer: 31 degrees</h3>

This is because rotations preserve angles. The angle measures won't change. That's why angle BCD is the same as angle B'C'D'. This applies to any rotation (regardless how much you rotate), any translation, any reflection, and any dilation.

Note: dilations will change the side lengths

The triangles below are similar. Find x showing the proportion and all work.
zavuch27 [327]

we are given that

two triangles are similar

so, the  ratio of their sides must be same

we get

\frac{2}{6} =\frac{x}{x+2}

now, we can solve for x

step-1: Cross multiply both sides

2(x+2) =6x

step-2: Simplify left side

2x +4 =6x

step-3: Subtract both sides by 2x

2x +4-2x =6x-2x

4 =4x

step-4: Divide both sides by 4

x=1

so,

x=1............Answer

If Joe's heart beats 1,200,703 times
professor190 [17]

11 days, 21 hours, and 52 minutes have elapsed

(this answer is assuming he would have a normal heart rate of 70 bpm)

First, you would divide 1,200,703 by 70:

1,200,703/70=17,152.9

This is the amount of minutes that have elapsed.

Then, you convert the minutes to hours by dividing by 60:

17,152.9/60=285.8816667 (285 hours and 52 minutes)

This gives you how many hours and minutes have elapsed.

Finally, you calculate the number of days that have elapsed by dividing 285 by 24 (there are 24 hours in a day):

285/24=11.875 (11 days and 21 hours).

Put all of the amounts together to get the final answer:

11 days, 21 hours, and 52 minutes have elapsed

Answer:

A = 201.0 mi^2

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

We know that r = 8

A = (3.14) *8^2

A = 3.14 * 64

A = 200.96 mi ^2
