Answer:
m<a = 30°
m<b = 90°
m<c = 60°
Step-by-step explanation:
Angles a, b, and c are all angles on a straight line.
Angles on a straight line add up to 180°.
Therefore, a + b + c = 180°
Given that a:b:c = 1:3:2, the measure of each can be calculated as follows:
Measure of each angle = the ratio proportion of that angle ÷ total ratio proportion * 180°
m<a =
m<b =
m<c =
Answer:
The correct answer is (b).
Step-by-step explanation:
A line is parallel to the axis if it has a slope equal zero. Then if we compute the slope of the line that joins the points
then
This implies that the line which that joins this points is parallel to the x-axis.
Observe that the slopes of the lines corresponding to the other items are nonzero.
