Answer:
15.
Step-by-step explanation:
L + L + W + w = 66
L= w+3
W+3 + w+3 + w + w = 66
4xw + 6 = 66
4xw = 66 - 6
4xw = 60
W + W +w +w =60
W= 60/4
W=15
L = 15+3 (=18)
15+15+18+18=66
Answer:
20.78
Step-by-step explanation:
sin a = perpendicular/ hypotenuse
where a is the base angle
here a = 60
sin 60 = 18/ x
since,
√3 x = 36
x = 36/ √3
x = 36/ 1.732
x = 20.78
Answer:
Each piece is 2 ft and 8 inches long.
Explanation:
12 inches are in a foot, so 12 times 8 equals 96.You then divide 96 by 3 which is 32.So 32 inches is 12in+12in+8in= 2feet 8 inches
Use inverse to solve this problem. Tan-1(5/27). =10.491 which rounded to the nearest degree equals 11.
