Find each measure,
What is the measure of angle 1
What is the measure of angle 2
What is the measure of angle 3
(Must show equation and steps so I can understand)

Answers

Answer:

Angle 1: 137 degrees

Angle 2: 47 degrees

Angle 3: 17 degrees

Step-by-step explanation:

To find angle 1, we must look at the supplementary pair given to us. One angle is 43 degrees. If we remember, a supplementary pair adds up to 180 degrees. To find angle 1, simply subtract 43 from 180 to get 137 degrees.

Equation: 180-43

To find angle 2, we must remember that all interior angles in a triangle add up to 180 degrees. We have two angles given, a right angle (90 degrees) and 43 degrees. Subtract 43+90 from 180 to get 47 degrees.

Equation: 180-43-90

To find angle 3, use the information gained from finding angle 1 (137 degrees) and the given angle (26 degrees) and subtract both measurements from 180. Doing this gets 17 degrees.

Equation: 180-137-26.

Hope this helped!

Angle 1: 137 degrees
Angle 2: 47 degrees
Angle 3: 17 degrees

Answer:

Angle A: 25

Angle B: 155

Angle C: 25

Angle D: 155

Step-by-step explanation:

Angle A is given so since c is across from a it is the same measurement.

Next to find b all you have to do is subtract angle A from 180 since A and B are supplementary.

180 - 25 = 155

Then D will just equal B.

B: 155, C:25, D: 155

The bike store marks up the wholesale cost of all of the bikes they sell by 30%.

Andre wants to buy a bike that has a price tag of $125. What was the wholesale cost of this bike?

If the bike is discounted by 20%, how much will Andre pay (before tax)?


(Please make sure to add a good explanation on how you found the answer because I have seen some where I didn't understand where a certain number came from.)

Answers

Answer:

Wholesale: $37.50

Discount: $7.50

Explanation:

*The wholesale cost of all the bikes they sell is 30%

*Andre wants to buy a bike for $125

*If the bike is discounted by 20%

[tex]\frac{30}{100}[/tex] = [tex]\frac{x}{125}[/tex] (solve for x)

100x = 125 x 30

100x = 3750

(x =  $37.50 for the wholesale)

For the discount, we need to find 20% of 37.5

An easier way we can do is to find 10% and to multiply by 2. So, move the decimal to the left of 37.5 and we get 3.75 and multiply by 2

3.75 x 2 = 7.5 ($7.50 the discount)

*

Answer:

$37.50

The measures of the angles of a triangle are shown in the figure below. Solve for x.
(3x+13)°
(8x+14)°
109°

Answers

(3x + 13) + (8x + 14) + 109 = 180°

(3x + 13) + (8x + 14) = 71°

11x + 27 = 71°

11x = 44°

x = 4

Answer:

x = 4

(3x + 13) = 25°

(8x+ 14) = 46°

Step-by-step explanation:

(3x + 13) + (8x +14) + 109 = 180 (Angles of a triangle)

11x + 136 = 180

11x = 180 - 136

11x = 44

x = 4

Substituting the value of x

(3x + 13) = 3×4 + 13 = 12 + 13 = 25

(8x + 14) = 8×4 + 14 = 32 + 14 = 46
