Answer:
5.1
Step-by-step explanation:
Before we calculate the y value for the point Q that is located two thirds the distance from point P to point R, we need to get the distance of point p from point R using the formula for calculatingf the distance between two points
D = √(x2-x1)²+(y2-y1)²
Given P(−2, 7), and R(1, 0)
RP = √(1-(-2))²+(0-7)²
RP = √3²+(-7)²
RP = √9+49
RP =√58
To get the y value for point Q that is located two thirds the distance from point P to point R, this will give
PQ = y = 2/3 of √58
= 5.1
Complementary angles are those angles whose sum is 90 degree.
The measurement of two complementary angles are

There sum have to be 90 degree. That is

Combining like terms ,

Moving 20 to right side

Dividing both sides by 5

So the measurement of the angles are

It is d- the function is a line
