Answer:
Step-by-step explanation:
Answer:
It is a right triangle, the right angle is at the point (-3, 5)
Step-by-step explanation:
The first step is to locate the points of the vertices in a plane, in this case they are (0.10), (-8.8) and (-3.5). The desmostration of this is shown in the attached image.
As we can see it is formed a right triangle (the figure outlined in red), and the rigth angle is the one at the point (-3,5).
Step-by-step explanation:
7=4y-13
7+13=4y
20/4=y
5=y
The equation would be 30+3m=162 then you solve the problem
