Remark
The only points that can lie on the y axis are a and d. There has to be a zero someplace. But the question is where?
The answer is in the graph below. (0,6) is in red and it is on the y axis.
(6,0) is blue and is on the x axis.
So if you want a point to lie on the y axis, the answer is that the x part of the point must be 0.
Answer D
Answer:
The required measure of angle 3 is 60°.
Step-by-step explanation:
We are given to find the measure of angle 3 from the figure if
m∠5 = 130° and m∠4 = 70°.
Let the measure of angle 3 be x°.
From the figure, we note that
angle 5 is an exterior angle and angles 3 and 4 are two remote interior angles of the triangle.
We know that
the measure of an exterior angle to a triangle is equal to the sum of the measures of two remote interior angles.
So, we get
Thus, the required measure of angle 3 is 60°.
