Please factor b^2+36=0

b=-√-36

b=+√36

Step-by-step explanation:

b^2+36=0

Substrate 36 from both sides

b^2=-36

Square root both sides

b=+or -√-36

So b=+√-36

Or b=-√-36

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
