Step-by-step explanation:
We are asked to explain why 
gives the area of a triangle with sides a and b and included angle theta.
We know that area of a triangle is equal to half the product of base and height of the triangle.
Upon looking at our given triangle, we can see that the base of the triangle is equal to 'a'.
The height of the triangle can be determined using sin(theta) as sine relates opposite side of right triangle with its hypotenuse.
Upon substituting our given values in area formula, we will get:
Hence, proved.
3 strips of 2.5 feet can be cut from the 7.5 feet long roll of ribbon.
Step-by-step explanation:
<u>DATA:</u>
Length of strips Eli need is 2.5 feet long
Length of roll of ribbon is 7.5 feet long
Number of strips that can be cut from the 7.5 feet long roll is x
<u>SOLUTION:</u>
To determine how many strips can be cut, divide total length of roll of ribbon by the length of strips needed.
Number of strips that can be cut = 
x = 
(expression)
x = 3 strips
Therefore, 3 strips of 2.5 feet can be cut from the 7.5 feet long roll of ribbon.

Answer:
Thank you bro.
Step-by-step explanation:
First :<span>Graph the solution set of the inequality
and interpret it in the context of the problem. For example: As a
salesperson, you are paid $50 per week plus $3 per sale. This week you
want your pay to be at least $100. Write an inequality for the number of sales you need to make, and describe the solutions.
second:</span>
<span> Simplify using the inverse of addition or subtraction. Simplify further by using the inverse of multiplication or division.
then find what you want to use!
