PLEASE HELP ME. ONLY GOT 10 MINS.
Vikki [24]

Answer:

Step-by-step explanation:

The ratio of the angle is how the angle relates to each other. Let's say that we try to relate Angle A, B, C and get 1 : 3 : 5. That means Angle B is three times Angle A and Angle C is 5 times Angle A

Thus we get the equation:

A

B = 3A

C = 5A

A + B + C = 180, since all the angles of the triangle is equal to 180 degrees

A + 3A + 5A = 180

9A = 180

A = 20 --> B = 3A = 60 --> C = 5A = 100

So Angle A is 20 degrees, Angle B is 60 degrees, and Angle C is 100 degrees.

Hope that helps!

30 pts! solve the following equation. (x - 18)^2 = 1
melamori03 [73]

Answer:

D - x = 19 x = -17

Step-by-step explanation:

Factor the equation to make the problem easier - you should have this:

(x - 18) (x + 18) = 1

Set each binomial to 1:

x - 18 = 1

x + 18 = 1

This should give you x = 19 and x = -17

A circle has a circumference of 10. It has an arc length of 9/2. What is the central angle of the arc in degrees?
dem82 [27]

Answer: The central angle of the arc is 162 degrees.

Step-by-step explanation: The information available are as follows;

Circumference of the circle equals 10. Length of an arc equals 9/2. The circumference of a circle is given as;

Circumference = 2Pi x r

That means 2Pi x r = 10.

Also the length of an arc along the same circle is 9/2. Length of an arc is calculated as;

Length of arc = (X/360) x 2Pi x r

Where X is the central angle of the arc

That means;

9/2 = (X/360) x 2Pi x r

We can now substitute for the known values as follows

Length of an arc = (X/360) x 2Pi x r

9/2 = (X/360) x 10

9/2 = 10X/360

By cross multiplication we now have

(9 x 360)/(2 x 10) = X

3240/20 = X

162 = X

The angle at the center of the arc is 162 degrees.
