Answer:
The answer to your question is SA = 2419.34 m²
Step-by-step explanation:
Data
a = 11.42 m
side = 11 m
height = 20 m
Formula
SA = 2B + PH
Process
1.- Calculate P
Perimeter = P
P = 7(11)
= 77 m
2.- Calculate B
B = Pa/2
= (77)(11.42)/2
= 879.34/2
= 439.67 m²
3.- Calculate 2B
2B = 2(439.67)
= 879.34 m²
4.- Calculate PH
PH = (77)(20)
= 1540 m²
5.- Calculate SA
SA = 879.34 + 1540
= 2419.34 m²
Answer:
b = 4 inches, c = ~5.66 inches
Step-by-step explanation:
The triangle is isosceles so b is equal to the adjacent side. Use the Pythagorean theorem to find c.
First you will use the slope formula:
M= Rise/Run = Y2-Y1/X2-X1
(0,13) (-4,10)
10-13
——— = -3/4 = 3/4
-4-0.
