Answer:
a. 20°
Step-by-step explanation:
The external angle T is half the difference of the intercepted arcs:
(92° -52°)/2 = 40°/2 = 20°
∠ETR = 20°
The line for y = -x + 3 is suppose to be negative slope. It’s -x so it goes down 1 right 1. Not up 1 right 1.

Answer:
The slope of a line that is perpendicular to the given line is
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:
Where "m" is the slope of the line and "b" is the y-intercept.
Solve for "y" from the equation of the line :
You can observe that the slope of this line is:
By definition, the slopes of perpendicular lines are negative reciprocal, then, the slope of a line that is perpendicular to the give line, is
