Answer:
You would use the cos function because you are given the adjacent side and you are finding the opposite side.
Step-by-step explanation:
SOH CAH TOA
Sin = O/H
Cos = A/H
Tan = O/A
O is the Opposite side
H is the Hypotenuse
A is the adjacent side
A. the first one is the answer
Step-by-step explanation:
Answer:
x = 5.5 (nearest tenth)
Step-by-step explanation:
let x be the length of 1 side
given area of square poster is 30 in²
and
Area = (length of 1 side )²
hence
30 = x²
x = √30
x = 5.4772
x = 5.5 (nearest tenth)
Answer:
84 cm^2
Step-by-step explanation:
The area of a triangle is
A = 1/2 bh where b is the length of the base and h is the height
A = 1/2 ( 5+9) * 12
A = 1/2 (14) * 12
A =84
