Keith bought a pair of jeans at a discounted price of $91.00. The original price of the pair of jeans was $130.00. If Keith got
the same discount on a t-shirt that originally cost $23.00, what is the discounted price of the t-shirt?
2 answers:
So first step would be to find the percent Keith got off for his jeans. To do that subtract 130-91 to get a difference of 39, then multiply 39 by 100 which is 3,900 and then divide by 130 which will give you 30. Which means Keith got 30% off his jeans. So, to find how much his shirt cost if he got 30% off you would multiply the original price, 23 by 0.3 or 30 percent and you get 6.9 then subtract 23-6.9 to get 16.1. So Keith bought his shirt for $16.10.

Question 1:
Look at the first attached image.
We want to solve for the height of the smaller building. Let's start by making a right triangle with angle of 15 degrees and adjacent side of 51 m.
Let's solve for the other leg. Multiply the tangent with 51 m to get the length of the other leg.
Now, subtract that from 207 to get the height of the smaller building.
That's your answer.
Question 2:
The angle of elevation is congruent to the angle of depression because they are alternate interior angles.
Thus, you can choose the 1st and 4th choices as your answer.
Question 3:
Look at the second attached image.
Angle E is congruent to angle D for the same reasons mentioned in the last question.
We can create an equation.
Distributive property
Subtract both sides by 1 and 2x
Since E and D are congruent, just plug this value into one of the equations for E or D. You get 46.
The third choice is your answer. Hope this helps! :)
