The sum of any triangle's three angles always add up to 180 degrees. Since you know two angles already ( 37 and 90 ), you can subtract those from 180 to find the remaining angle which is 53 degrees. The answer to your question is 90 degrees and 53 degrees.
Answer:
Step-by-step explanation:
To compute x times y must use foil on the right hand side.
First: 
Outer: 
Inner: 
Last: 
------------------------------------Add like terms:
----------------
Multiply top and bottom by bottom's conjugate:
Foil the top and just do first and last of Foil for the bottom since the bottom contains multiplying conjugates:
Replace 
with -1:
Answer:
You can put this equation into point slope formula which is…
y-y1= m(x-x1)
Whilst m is slope
x1 and y1 (x1, y,1)
So in this case lets find the slope first.
Slope is calculated by y2-y1/ x2-x1
Can be any point.
7-(-1) / 1-(-3)
Which is
2
Slope is 2
So plug it in.
y-(-1)= 2(x-(-3)
Solve
y+1= 2x+6
isolate y
Y=2x+5
Your equation is y=2x+5
