The first step we take is to factor out a GCF:
2d(d³ + 3d² - 9d - 27)
Now, we can factor what's in the parenthesis by grouping (don't forget to keep the 2d we factored out):
2d[d²(d+3) -9(d+3)]
2d(d²-9)(d+3)
d²-9 can still be factored because it is the difference of two squares:
2d(d+9)(d-9)(d+3)
That is the completely factored form.
Answer:
Both triangles have acute angles
The answer is 58 i hope this helped you and didn’t make you fail lol
The whole triangle and the triangle with the angle K are both isosceles triangle which means two angles are equal.
The total triangle angle is 180. Using this you can find the K.
