Answer:
a) 5
Step-by-step explanation:
f(5) = 3x – 5/ 2
f(5) = 3(5) – 5/ 2
f(5) = 15 – 5/ 2
f(5) = 10/ 2
f(5) = 5
The ratio of interest can be found for collinear points by considering only one of the coordinates. Let's look at the x-coordinates.
(Tx -Mx)/(Dx -Mx) = (1-(-3))/(9-(-3)) = 4/12 = 1/3
Then the ratio of interest is MT:MD = 1:3.
First you need to solve for "x": 6x+3=8x-21, 3=2x-21, 24=2x, x=12.
Then plug in number 12 to your equation: 6(12)+3=75;
Just to make sure that I solved correctly for x, plug in 12 into the second equation: 8(12)-21=75.
Yahoo, the x is 12 and angle measure is 75°.
