I'm ASSUMING this is a 45-45-90 right triangle and that DF is the hypotenuse.
With that said. Angle F = 45 means that angle = 45 and angle E = 90 degrees.
There is only one rule for 45-45-90 right triangles:
hypotenuse = √(2) * leg
Given the hyp = 16
16 = √(2) * leg
divide both sides by √(2)
16/√(2) = leg
Rationalize the denominator
16√(2)/(√(2)*√(2) =
(16√(2)) / 2 =
8√2
The first answer is 9x + 2y
the second answer is 3y
Answer:
y=5+2x
Normally I would explain it, but im in a bit of a hurry today. I apologize for the inconvenience!
It’ll be C all the numbers in between -7 and 7
3xy + 4x -16 ...... I hope that helps .
