Haven't been taught this; but from what I searched up; I think the postulate for proving these shapes' congruence is Hypotenuse/Leg. I have no exact idea however. Correct me if I'm wrong :/
Answer:
. (5,20)
Step-by-step (x,y)=(5,20)
Yes, I think the answer is y = 7. The line x = 4 runs vertical (because all of the points in that line have an x-value of 4) so any line that is perpendicular to it has to be horizontal. Any line that is horizontal is in the form y = (some number). In order for the new line to run through the point (5,7) it would have to have the same y-value as that point, which is 7. So the new line is y = 7. Hope this helps :) (P.S. try graphing them both if you need a visual.)
Answer:
A: 65° B: 65° C: 125° D: 125°
Step-by-step explanation:
It is an equilateral(shown by the two dashes) and all angles in a triangle add up to 180°.
180-50 divided by 2 to give you A and B angles.
Then angled on a straight line add up to 180° so if you take angle A away from 180° you will get the answer to angle C.
The same for angle D.
Step-by-step explanation:
y = 5x - 3 is in slope-intercept form.
The slope of this given line is 5,
=> Parallel line will also have slope 5.
We have y = 5x + c, where c is a constant.
When x = 4, y = 7.
=> (7) = 5(4) + c, c = -13.
Therefore the answer is y = 5x - 13.
