Angles STU and UTV combine to form right angle STV. Which expression could be used to find the measure,in degrees,of angle UTV?

1 answer:

8 0

STV=STU+UTV

But,
STV=90° and STU = 75°

Therefore,
90=75+UTV => UTV = 90-75

Therefore, expression A is the one that can be used to find UTV.

Step-by-step explanation:

To graph a linear function like y=mx+b, find m and b. Here m = -1/2 and b= 2 for $y=-\frac{1}{2}x+2$ .

Start at (0,2) on the y-axis and plot a point. Then move from that point one unit down and over to the right 2. Plot the point and connect.
