Answer:
92.5 cm²
Step-by-step explanation:
Lets take this step by step
Bottom rectangle is 2 by 5, so then 2*5 = 10
Large rectangle is 8 by 9, so 8*9 = 72
The triangle is 7 by 3, you get the 7 by subtracting the 5 side from the square because using the square you can tell that the height is 9 - something.
The 5 you get is from subtracting the cut part that you might have made because the height of that is 2, therefore you cut off 2 from 7 making it 5
Triangle area is h*b / 2, therefore 7*3 = 21/2 = 10.5
Add them all together, 10.5 + 10 + 72 and you get 92.5
Answer:
886.3 feet
Step-by-step explanation:
cos(10°) = d/900
d = 900 cos(10°) = 886.3 feet
Think of it this way. an reflection is just a mirror image of the original shape. you are basically just flipping it over the x-axis.
Answer:
Step-by-step explanation:
The area of the parallelogram can be found using the formula:
Area = base x height.
The area is 24, and the height is 3. Isolate the base. Note the equal sign. What you do to one side, you do to the other. Divide 3 from both sides
24 = b x 3
24/3 = 3b/3
divide
b = 24/3
b = 8
8 feet is your base
hope this helps
