Step-by-step explanation:

4x+3x-5+2x+5=180 (to find x)

9x=180

x=20

Therefore DEF=AEC(vertically opposite angles are equal)

AEC=DEC

=4x +3x-5

=4(20)+3(20)-5

=135°

If UT is a midsegment of QRS, find SQ<br> A. 8 <br> B. 10 <br> C. 16 <br> D. 20
sladkih [1.3K]
If UT is the midsegment of QRS, then SQ = 2(2x + 2) = 4x + 4
Then,
(3x + 1)/(7x - 1) = (2x + 2)/(4x + 4) = 1/2
2(3x + 1) = 7x - 1
6x + 2 = 7x - 1
7x - 6x = 2 + 1
x = 3

Therefore, SQ = 4(3) + 4 = 12 + 4 = 16.
