The difference of complimentary angles is 10 degree. find the measure of the angles.
Ivahew [28]

Answer:

The angles are 50 , 40

Step-by-step explanation:

Let 'x' be an angle.

So, its complementary angle = 90 - x

Difference of complimentary = 10

x - (90 - x) = 10

x - 90 + x = 10

x + x - 90 = 10

2x -  90 = 10

       2x = 10 +90

       2x = 100

         x = 100/2

        x = 50

So, the angles are 50 , 40

Answer:

Each pizza have <u>8</u> slices.

Step-by-step explanation:

Given:

At a party to celebrate a successful school play, the drama club bought 9 large pizzas.

Each pizza had s slices.

All together, there were 72 slices of pizza for the club to share.

Now, to find slices each pizza have.

Number of slices each pizza have = s.

Number of slices of pizza altogether = 72.

Total number of pizza = 9.

Now, to write an equation of this situation:

9\times s=72

9s=72.

So, to get the slices each pizza have we solve the above equation:

9s=72

<em>Dividing both sides by 9 we get:</em>

s=8.

Therefore, each pizza have 8 slices.
