1. (The base on top is 15 ft.
To find the base on the bottom you have to first find the length of the right side of the triangle. 7 - 4 = 3. Then, square both sides of the triangle and add them together. 15^2 + 3^2 = 234
Next take 234 and find its square root = 15.3. The bases of the trapezoid are 15 and 15.3)
2. (Both bases and the height.)
3. (2l + 2w does not belong, all of the equations are formulas for area but that one is perimeter)
Answer:
b=20
C=160
Step-by-step explanation:
160+b= 180 (sum of angle on the straight line)
b=180-160
b=20
b+c =180 (sum of angle on the straight line)
20+c=180
c=180-20
C=160
