Dexter got a raise in his hourly pay, from $12.75 to $16.30. Find the percent change. Round to the nearest tenth of a percent.

27.8

Step-by-step explanation:

16.3 - 12.75 = 3.55

3.55 ÷ 12.75 = 27.8

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.

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12
