Answer:
Step-by-step explanation:
QR = 27 ÷ 2 = 13.5
I think u forgot to put pic for we can see the triangle
Equation = 12 - -24 = ?
After keep, change, flip: 12 + 24 = ?
Answer = 36
D = 171 - (61+53) = 171 -124 = 47
E = 171 - 90 = 81
A = 81 - (34+24) = 81 - 58 = 23
B = 61 - 23 = 38
C = 90 - (33+ 38) = 90 - 71 = 19
answer is B.
I know the answer is 22.2
