Remember that the angles in a triangle add to 180 degrees. So, to solve, you add the two angles you have and subtract that difference from 180.
Answer:
1,800 bricks are needed
Step-by-step explanation:
First convert the Length and width of the sidewalk into inches
Entire Sidewalk: L= 100x12 =1200in and W= 4 x 12 = 48in
Then we know Area = LxW, so we will do this for both the sidewalk and the brick.
Area of sidewalk: 1200 x 48 = 57600
Bricks ( no need to convert since the measurements are already in inches): 8 x 4 = 32
Now we will divide the area of the entire sidewalk by the area of a single brick to find out how many bricks you need to complete the whole sidewalk:
57600/32= 1,800 bricks

<span>To convert percentages to decimal points, divide the percentage to 100. That is, 65</span>÷100 and 55÷100. The answer would be 0.65 and 0.55. If the question asks for three decimal places, add 0 to the last digit of your decimal to make it three because it will be counted. So 0.65 becomes 0.650 and 0.55 becomes 0.550.
190+38=228
