<h3>
Answer:</h3>
PR ≈ 14.50
<h3>
Step-by-step explanation:</h3>
Since ∠Q is a right angle, the area can be found from ...
... A = (1/2)bh = (1/2)(QP)(PR)
From trigonometry, we know ...
... QP = PR·cos(P) = PR·cos(36°)
... QR - PR·sin(P) = PR·sin(36°)
Substituting these values and the given area into the area formula gives ...
... 50 = (1/2)(PR·cos(36°))(PR·sin(36°))
... 100/(sin(36°)cos(36°)) = (PR)²
... PR = 10/√(sin(36°)cos(36°))
... PR ≈ 14.5015
Answer:
the answer is c)SAS
Step-by-step explanation:
as the sides are already given and and both angles will be equal as vertically opposite angles (VOA)are always equal.
Down because the slope is negative
<h3>
Answer: x-y years old</h3>
========================================================
Explanation:
Let's use numbers in place of the variables
Let's say Anna is 25 years old and her sister Jane is 5 years younger.
This means Anna was 25-5 = 20 years old when Jane was born.
-------------------------
As another example:
Anna = 37 years old
Jane = 10 years younger
Anna was 37-10 = 27 when her sister was born
--------------------------
The examples show that all we do is subtract the x and y values to figure out how old Anna was when her sister was born.
For the first example, we basically did x-y = 25-5 = 20
The second example was x-y = 37-10 = 27
A variable is placeholder for a number. Think of it as a box where a single number will go inside.
