I need to know this ASAP I need to get through this lesson before Friday

It is C.

Step-by-step explanation:

So,A triangle is equal to 180 and you would add up the numbers you already have which equal 145.180-145= 35° and thats why the last letter would be 35° in your answer and be correct which would be that m<F=35° is the same as ABC in the last letter. Since,<B is the second letter in ABC and so is <E in DEF and have the same degree that would be the same as well so I hope that helps:)

c

Step-by-step explanation:

the angles in a triangle have to add up to 180°

65 + 80 = 145

180-145 = 35

the missing angle is 35°

choice c matches because it has 2 of the same angle measures, which means they all have to be the same

this is a good question! i'll do some research and come back when i have the answer!
