The area for the figure is 146
Answer: 
b) x = 12 RS = 20 ST = 40
c) x = 7 RS = 6 ST = 11
<u>Step-by-step explanation:</u>
Use the Segment Addition Postulate: RS + ST = RT
a) (2x - 10) + (x - 4) = 21
3x - 14 = 21
3x = 35
x 
RS = 2x - 10




ST = RT - RS


Use the same formula to solve for b and c
Answer:
y = 32
Step-by-step explanation:
32 x 2 = 64
