The answer is B I hope you get it.
Answer:
Option C.
Step-by-step explanation:
Given information: In triangle ABC, ST║AC, SB=10 ft, BT=9 ft and CT=2.7 ft.
Triangle proportionality theorem: If a line segment parallel to a side of a triangle then the line segments divides the remaining sides proportionally.
Using triangle proportionality theorem we get


On cross multiplication we get


Divide both sides by 9.

The length of SA is 3ft.
Therefore, the correct option is C.
Answer:
Zack will need 17 1/2 ft of fence
Step-by-step explanation:
To calculate this we will first pass the numbers to complete fractions
5 1/4 ft = 21/4 ft
3 1/2 ft = 7/2 ft
We have to add 2 times each side
21/4 ft + 21/4 ft + 7/2 ft + 7/2 ft =
Now we have to pass all the fractions to the same denominator
21/4 ft + 21/4 ft + 14/4 ft + 14/4 ft =
70/4 = 17 1/2
Zack will need 17 1/2 ft of fence
Q55.
UTA+ATS=UTS
x+18+120=12x+17
x+138=12x+17
12x-x=138-17
11x=121
x=121/11
x=11
mUTA=x+18
put the value of x
11+18
mUTA=29
Q57.
AQP+RQA=RQP
9x+2+75=1+28x
9x+77=1+28x
28x-9x=77-1
19x=76
x=76/19
x=4
mRQP=1+28x
put the value of x
1+28(4)
1+112
mRQP=113
