All quadrilaterals has a total measure of angle equal to 360 degrees. In the parallelogram ABCD, m<B = m<D = 41. So if m<B = m<D = 41, we have 41 + 41 = 82 degrees. Since the parallelogram is a quadrilateral, it has a total measure of angle of 360 degrees. So 360 – 82 is equal to 278 degrees. If the measure of angle C is equal to the measure of angle A, divide 278 by 2. We get 139 degrees. To confirm if the parallelogram ABCD has a total measure of 360 degrees, add 41 + 41 + 139 + 139 = 360 degrees.

A frozen pizza is on sale at a 25% discount. Find the sales price of the pizzas if it normally sells for $4.85.
bonufazy [111]
The best thing to do here is to divide $4.85 by 10, and then multiply it by 2.5. $4.85/10= $0.48. $0.48x2.5= $1.20 Therefore,the discount is $1.20, you've then got to subtract this from $4.85. $4.85-$1.20= $3.65 $3.65 is the sale price of the pizza. Hope this helps :)

Here are four digits.
Bogdan [553]

Answer:

A: 357

(1) 9641

Step-by-step explanation:

With A you really just want to go from the smallest number up so it would be the smallest number possible.

<em>EX.</em> 357 vs. 736   357 is smaller

With 1 you have to go from the highest number to lowest number to get the biggest answer possible.

<em>Ex.</em>  9641 vs. 1946    9641 is larger.
