Answer:
6.69ft
Step-by-step explanation:
Answer:
y = 6.69 ft
Step-by-step explanation:
Given : A right angled triangle with perpendicular is y ft and hypotenuse is 15 ft.
We have to find the measure of y.
Consider the given triangle
Using trigonometric ratio,
Sine of angle is the ratio of perpendicular to its hypotenuse.
Thus,
For
We have perpendicular = y ft and hypotenuse = 15 ft.
Multiply both side by 15, we have,
Simplify, we have ,
y = 6.69
Thus, y = 6.69 ft
<u>Answer:</u>
(-1, -1)
<u>Step-by-step explanation:</u>
The solution is where both lines intercept on a graph.
Solution: (x = -1, y = -1)

The sweater has a discount with is 40% of the regular price.
She saved 20 dollars on the sweater that she bought.
Let's solve for the original price of the sweater then,
=> 20 dollars = 40%.
Let's look for the 60%.
=> 20 / 4 = 5 dollars is the 10% of the sweater's original price.
=> 5 dollars * 10 = 50 dollars
=> Thus the original price of the sweater is 50 dollars.
