Answer:
A = ((a+b)/2)h
Step-by-step explanation:
a and b are base (the top and bottom)
h is height
Answer:
7 x 4 = 28
28 x 1/2(dividing by 2) = 14, 14 x 2(two triangles) = 28
4 x 5 = 20(area of square in the middle)
5 x 8 = 40(area of square on one side), 40 x 2 = 80(area of squares on both sides)
Now lets add the given areas:
28 + 20 + 80 = 128 square is your answer.
Simplified: 13/50
Not Simplified: 26/100
Answer:
45:18:36
Step-by-step explanation:

substitute x back into 5x:2x:4x
Therefore, 99 in the ratio of 5:2:4...
45:18:36
Answer:
in a triangle the angles have to measure to 180 degrees.
62 + 90 (right angle Q) =152
180 - 152 = 28
Angle S = 28
