Answer:
Step-by-step explanation:
It is important to remember that, by definition, the measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles.
In this case we can idenfity that the angle is an exterior angle of the triangle QRT. Then:
Where:
Substituting values and solving for "x", we get:
Then:
The sum of the interior angles of a triangle is 180°, therefore:
Solving for , we get:
Answer:
Step-by-step explanation:
Given:
The function is given as;
In order to find the inverse, the steps to be followed are:
Step 1: Replace by
. This gives,
Step 2: Switch 'y' by 'x' and 'x' by 'y'. This gives,
Step 3: Solve for 'y'.
Dividing both sides by 8, we get:
or
Taking square root on both sides, we get:
Now, we replace 'y' by .
Therefore, the inverse of the given function is:
