suppelementary angles are angles that add to 180

remember that a straight line is 180 degrees so some angles that are supplementary are 1 and 2, 5 and 6, 1 and 5, 6 and 2, 3 and 7, 4 and 8, 7 and 8, 3 and 4


vertical angles are across from each other when 2 lines cross, they are like 5 and 2, 6 and 1, 7 and 4, 8 and 3

The supplementary angles are 1 and 5 , 6 and 2 because they add up to 180.

And the vertical angles are 1 and 6, 2 and 5 which makes the pairs congruent.

$676.

If the sale price of the coat is $169, you are looking for the original price. I like to think about it in the sense that if an item is 75% off, you are paying 25% of the original amount. Using that logic, in order to determine the sale price you would use the equation

Original price * 25% = $169

To solve for the original price:

Original price = $169/.25 = $676.

vivado [14]

Answer:

$1,061

Step-by-step explanation:

2% of 1000 is 20.

If 2% is compounded yearly, then

year one- $1,020

year two- $1,040.40

year three- $1,061.21

Rounded to the nearest whole dollar, Elaine would have $1,061 in her savings account after three years.

Britton rotated trapezoid ABCD 180° on the coordinate plane. If angle B is 20° and angle D is 90°, what is the degree measuremen
olasank [31]

Answer:

The answer is 20 degrees

Step-by-step explanation:

A trapezoid is a quadrilateral with four angles and the sum of the four angles is 360 degrees.

Britton rotated the trapezoid ABCD 180º, but we were not told that he tampered with the angles size or shape, we can now agree that it is still the same trapezoid that was rotated without any alterations in angles, size and shape.

Since we've been given that the angle B is 20º, and the measurement was not altered when rotating the trapezoid. Therefore the angle B' will also be 20º.

I hope this helps.
