Answer:
A ≈ 65.4°
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the trig relations associated with pairs of sides. For angle A, given sides b and c are the adjacent side and the hypotenuse, respectively. The appropriate relation is ...
Cos = Adjacent/Hypotenuse
cos(A) = b/c
A = arccos(b/c) = arccos(2.5/6)
A ≈ 65.4°
Answer:
161 6/72
Step-by-step explanation:
50 5/8 plus 50 5/8 = 100 10/8 = 101 2/8
30 2/9 + 30 2/9 = 60 4/9
add them together which comes out to 161 6/?
Use LCM or least common multipule and it should come out to 161 6/72
Let the DVD = x
let the CD = y
x+y = cost
Answer:
(5-2a+6b)/2
Step-by-step explanation:
According to PEMDAS, we would multiply 2 by (a+3b) first. This would equal 2a+6b. Since this is being subtracted from 5, the numerator would equal 5-2a+6b. This would bring the simplified answer to (5-2a+6b)/2
