If M is a midpoint of PQ, then we can use the formula of a midpoint:

We have the endpoints (-2a, 0) and (0, 2b). Substitute:

<h3>Answer: M(-a, b)</h3>
Answer:
D. 24
Step-by-step explanation:
Angles are the same, so 84 = 3x.
To get x alone, you divide 3 by both sides.
84/3 = 24
24 = x.
The value of the angle R in the right triangle PQR is sin⁻¹ 6 / 8
The situation forms a right angle triangle.
<h3>How to find an angle in a right triangle?</h3>
The angle R can be found as follows:
using trigonometric ratios,
sin R = opposite / hypotenuse
Therefore,
opposite sides = 6
hypotenuse = 8
sin R = 6 / 8
R = sin⁻¹ 6 / 8
