Kiran is trying to prove the isosceles triangle theorem. In other words, he wants to prove that Angle ABC = Angle ACB. He first draws triangle ABC such that AB is congruent to AC. He then decides to draw in a line
that goes through A and intersects BC at point D.

a. What is one of the ways Kiran can define this line that he drew that could help
him in his proof?

b. Finish the proof of the isosceles triangle theorem.

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.

step-by-step explanation:

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
