Answer:
x = 73.17
Step-by-step explanation:
To solve this problem we are going to have to use trig function
The three main trig functions are
Sine = Opposite / Hypotenuse
Cosine = Adjacent / Hypotenuse
Tangent = Opposite / Hypotenuse
( where hypotenuse = longest length , opposite = side length opposite of angle and adjacent = other side length )
Here, we are given two side lengths and we want to find an angle.
We are given the hypotenuse and its adjacent ( we know this because we are not given its opposite )
When you have the adjacent and hypotenuse you use cosine.
So we have Cos"x" = adj / hyp
adj = 22 and hyp = 76
So Cos"x" = 22/76
==> take the inverse of cos to both sides
x = 73.17 ( rounded to the nearest hundredth )
and we are done!
X -> her money;
( 1 / 4 )*x = x / 4 for a pair of shoes;
( 1 / 5 )*x = x / 5 for a shoulder bag;
x - x / 4 -x / 5 = 20x / 20x - 5x / 20x - 4x / 20x = 11x / 20 the remainder;
11x / 20 - ( 3 / 8 )*x = 11x / 20 - 3x / 8 = 22x / 40 - 15x / 40 = 7x / 40 for her dress;
She pay 7 / 40 of her money for the dress.
