The quotient of a number and two imcreased by five is 10 equation

x/2 + 5 = 10

Subtract 5 from both sides.

x/2 = 5

Multiply both sides by 2.

x = 10 (This is your answer.)

c is the final answer! : )

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
