Answer:
1
Step-by-step explanation:
We have the function
and we want to know the value of .
The first step is to find ; we can subtract 1 from it at the end! But what does
mean?
Basically, we're saying <em>"what is the value of the function when </em><em> ?"</em>
So, we simply replace with 3 in the function, and we get:
.
Finally, we subtract 1 to find .
Given:
The figure of a rhombus QRST.
To find:
A. The value of x.
B. The measure of angle RQP.
Solution:
A. We need to find the value of x.
We know that the diagonals of a rhombus are perpendicular bisectors. It means the angles on the intersection of diagonals are right angles.
[Right angle]
Divide both sides by 5.
Therefore, the value of x is 15.
B. We need to find the measure of angle RQP.
From the given figure, it is clear that
Putting , we get
Therefore, the measure of angle RQP is 33 degrees.
