the diagonal of the triangle representa the lenght of the ladder and is 12 foot
as the Sen alpha = CO/H, OF THIS FORMULA , CO IS THE HICK OPPOSITE AND REPRESENT THE HEIGHT
CO = Sen alpha*H = Sin (60°)* 12 = 10,39 FOOT
Answer:
174 centimeters squared
Step-by-step explanation:
2×(2×5 + 2×11 + 5×11)
= 174 centimeters squared
would it be seven ÷ by three
M=5(d+k)
Distribute the 5
M=5d+5k
-M -M
—————-
0=5d+5k-M
-5d -5d
———————-
-5d=5k-M
—— ——-
-5 -5
d = -k-1/5M
