Answer:
See below
Step-by-step explanation:
a = 15 sqrt 2 sin 45
= 15 sqrt 2 * sqrt( 2 ) /2 = 15 * 2 /2 = 15
sin 60 = a/c
sqrt(3)/2 = 15/c
c = 15 / ( sqrt(3)/2) = 30 / sqrt 3 = 30 sqrt 3 /3 = 10 sqrt 3
Answer: 288.74
Step-by-step explanation:
You would use the tangent first, because the opposite of 40 would be x and the adjacent would be 30ft
Answer:
7x - 42
Step-by-step explanation:
It's B because 5 x 4 = 20 and 9 x 5 = 45
When you add them together you get 65
