Step-by-step explanation:
Remark
The adjacent side is one of the two sides making up the acute angle in a right triangle. The second side is the Hypotenuse.
Givens
Cos(C) = side Adjacent / Hypotenuse
Cos(49) = 0.6561
Side Adjacent = 18
Solution
Cos(C) = side adjacent / Hypotenuse Multiply both sides by the hypotenuse
Hypotenuse * Cos(C) = Side Adjacent Divide by Cos(C)
Hypotenuse = Side Adjacent / Cos(C)
Hypotenuse = 18 / Cos(C)
Hypotenuse = 18 / 0.6561
Hypotenuse = 27.437
Answer:
x≈11.8
Step-by-step explanation:
Since this is a right triangle, we can use cosine to find the length of CD.
First, set up an equation, then solve:
cos(49°)=18/x
x=18/cos(49°)
x≈ 11.80906252
rounded to the nearest tenth of a foot:
x≈11.8

as number of terms can't be negative.
9x + 3 = 7x +19
2x + 3 = 19
2x = 16
x = 8
So, x (8) is the number of chairs in each row with these setups.
Plug 8 into one of the equations and you will find how many chairs total there are.
9(8) + 3 = 75
There are 75 chairs total
