In geometry, you will learn that supplementary angles add up to 180 degrees. Therefore, if two angles have exterior rays that li

e on a line, those two angles are supplementary and they add up to 180 degrees. Supplementary angles are shown below:
You can use this information to set up an equation to solve the problem below for x.

Angle 1 has measure "x". Angle 2 has measure "2x + 30". Find x.

Hint: use the fact that these two angles lie on a line and are therefore supplementary to write the equation:

x + 2x + 30 = 180

Then solve for x.

Orchid wants to retile her bathroom floor, which has an area of 40 square feet. She is deciding between two types of custom tile
Gre4nikov [31]

Your answer is the second option, she should choose the rectangular tiles because the total cost will be $8 less.

To find this answer we need to first find the total cost for using square tiles, and the cost for using rectangular tiles, and compare them. We can do this by finding the area of each tile individually, calculating how many tiles we would need, and multiplying this by the cost for one tile:

Square tiles:

The area of one square tile is 1/2 × 1/2 = 1/4 ft. Therefore we need 40 ÷ 1/4 = 160 tiles. If each tile costs $0.45, this means the total cost will be $0.45 × 160 = $72

Rectangular tiles:

The area of one rectangular tile is 2 × 1/4 = 2/4 = 1/2 ft. Thus we need 40 ÷ 1/2 = 80 tiles. Each tile costs $0.80, so the total cost will be 80 × $0.80 = $64.

This shows us that the rectangular tiles will be cheaper by $8.

I hope this helps! Let me know if you have any questions :)

25% of 500 is 12, divide 500 by 4

35% is 25% + 10% = 125 + 50 = 175
