x=___ Write the answer in decimals

Answer 1

26

Explanation:

9=x+1

5=10÷3

9=x+1

5=3.333°

Now you need to find scale factor (sf)

5÷3.333°=1.5

SF=1.5

9÷3.333=2.7

2.7-1=1.7

x=1.7

Answer 2

x = 5

Explanation:

Given PQRS ~ UVWT and PQ = 5, RS = 9, UV = 10/3, WT = x+1, you want the value of x.

Similar polygons

Corresponding side lengths of similar polygons are proportional. This means ...

WT/UV = RS/PQ

(x+1)/(10/3) = 9/5 . . . . . . . . . . . substitute given values

Multiplying by 10/3 gives ...

x +1 = (10/3)(9/5) = 6

x = 5 . . . . . . . . . subtract 1
