Answer:
D.
Step-by-step explanation:
The number which multiplies x is the slope of the graph so 13x becoming 3x means the slope of the graph will change.
The angles of the triangle are 39°, 51°, and 90°.
Step-by-step explanation:
Step 1:
The sum of all the angles in any triangle is equal to 180°.
We have two of the three angles in terms of x while the third angle is not given directly. Since it is a right-angled triangle, one of the angles equals 90°.
So the angles of the triangle are
and 
Step 2:
Now, we substitute all the angles to a sum of 180 to determine the value of x.


So x = 13°. The angles are

The angles of the triangle are 39°, 51°, and 90°.
