Question

Can you explain this question!!
On how I got 173 degree from this answer (dont upload an image say this in the question)

Answer 1

Answer:

Step-by-step explanation:

well first you solve the other angles in the other triangles first like this

first triangle 73+79+x=180

152+x=180

x=180-152

x=28 then

second triangle

37+96+y=180

133=y+180

y=47

then x+y=28+47=75

then,112+75+AED=360

AED+187=360

AED=173 degrees

Answer 2

Answer:

I beg to differ. The answer is 75°.

Step-by-step explanation:

Use the Angle Sum Property in Triangle ∆EBC

=180°-(73°+79°)

=47°- 1.

Use the Angle Sum Property in Triangle ∆EDC

=180-(96°+37°)

=47°- 2.

Adding 1. and 2.......

=47°+28°

=75°
