Choices for question #1:
a. x = 3, st = 24
b. x = 3, st = 36
c. x = 8, st = 24
d. x = 8, st = 36
choices for question #2:
a. x = 36
b. x = 3
c. x = 12
d. x = 49

Question #1 choice A x=3, ST=24 and Question #2 choice C x =12

Step-by-step explanation:

Question #1

T midpoint so ST=TU and 8x = 2x+18

8x =2x+18

8x-2x=18

6x=18

x=18/6

x=3

so ST= 8x=8*3=24

choice A

Question #2

M midpoint of AB so AM=MB and 4x+1=7x-35

4x+1=7x-35

1+35=7x-4x

36=3x

36/3=x

12=x

choice C

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
