Answer:
The value of
which makes the equation true.
Step-by-step explanation:
Given the equation

We have to find the value of r for which the equation must be true.
solving the equation

Multiply both sides by -11


Therefore, the value of
which makes the equation true.
<u>VERIFICATION:</u>
Putting
in the equation


∵ 
L.H.S = R.H.S
Therefore, the value of
which makes the equation true.
The angles in degrees to radian is as follows:
-54 degrees = -3π / 10 radian
<h3>How to convert from degree to radian?</h3>
The measurement is in degrees. Let's convert it to radian with respect to π.
Therefore,
180 degrees = π radian
-54 degrees = ?
cross multiply
Hence,
angle in radian = -54 × π / 180
angle in radian = - 54π / 180
angle in radian = - 6π / 20
angle in radian = -3π / 10 radian
