1.Can a triangle have angles equal to

a. 55°, 65°, 70°

b. 53°, 64°, 73°

c. 80°, 105°, 5°

2. In (triangle)△DEF, <D, <E and <F -44° (deg), Find <D and <E

1) The angles in a triangle sum to 180 degrees, so which of a, b and c do?

2) Please retype this so we can understand it.

and on number two.. that's what the paper says.. but i think it meant <F is equals to -44 degrees

Answer "no", and give the reason.on number one.. i dont get it.. they all sum 190.. what do i do?

What does it mean about angles D and E?and on number two.. that's what the paper says.. but i think it meant <F is equals to -44 degrees

Also a triangle cannot have an internal angle of -44 degrees.

(Try typing exactly what it says in the question together with extra information that is common to the question set etc)

Is that the

here it is.. im so sorry i thought it says negative..

\(\angle D+\angle E=180^{\circ}-44^{\circ}=136^{\circ}\)

here it is.. im so sorry i thought it says negative..

Also since we are told \(\angle D=\angle E\) these are both \(??^{\circ}\).

It would save a lot of time if you took more care to post exactly what you are asked.
