Answer:
110 degrees.
Step-by-step explanation:
Angles 2 and 3 are supplementary, and angles 8 and 7 are supplementary.
Angles 3 and 7 are equal.
If angle 8 is equal to 70 degrees, angle 3 is equal to 110.
It would be -4
4(2) + 5(-4) = -12
-2(2) + 3(-4) = -16
Answer:
A.88°
Step-by-step explanation:
Given,
RT is the diameter of the circle with center Q.
We have to find the measure of ∠RQS.
Solution,

Since RT is the diameter. That is it makes a straight angle at the center Q.
And measure of straight angle is 180°.
So we can say that ∠RQS and ∠SQT makes a straight angle.

Now substituting the given values, we get;

We get the value of 'x'.
By substituting the value of x, we can find the measure of ∠RQS.


Hence the measure of ∠RQS is 88°.
The answer is the 2nd choice.
