All the steps were correct except the final statement. The mistake was in Line 6.

Line 6 triangle ABC is congruent to triangle EFD by SAS.

<span>This does not follow. The SAS postulate states that if two sides and the included angle of one triangle is congruent to two sides and the included angle of another triangle. The student only proved that one side of the triangle (AC) is congruent to the side of another triangle (EF) .</span>

I really need help with the question above! This is my second time asking. Am I right? If not please give me the correct answer
vredina [299]
Hey there! :D

Pay attention to the given angles. 

We know that a circle is equal to 360 degrees. 

We know two angles, and the other 2 are the same measure. 

170+44= 214

Subtract that from 360, since that is what the circle equals. 

360-214= 146

Divide that by two, since there are 2 equal angles left. 

146/2= 73

<DOB= 73 degrees. 

You were correct, so good work!

I hope this helps!
