Need asap. i don't know what the answer is. asap

Yeah it is D i hope this helps u

43.25 degrees   B.

Step-by-step explanation:

This is an isosceles triangle (DF = EF) and so the 2 base angles are euql .

So m < x = (180 - 93.5) / 2

=  43.25 degrees

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
