Type the correct answer in the box. use numerals instead of words. if necessary, use / for the fraction bar. the measurement of angle b is °. the measurement of angle a is °. the measurement of angle c is °.

B = 135

A = 60

C = 75

Hope this helps

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.

what is all that apply?
