What is the sum of the measures of the exterior angles of this triangle?

Answer

360°

Explanation

First get the values of the unknown angles.

c = 180 - 112 = 68

b = 51 + 68 = 119 (Sum of opposite interior angle is equal to opposite exterior angle).

The adjacent exterior angle to 51 is (180-51) = 129.

Sum of exterior angles;

129+112+119 = 360°

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.
