Step-by-step explanation:
idk i just guessin
she should use 2 by 6
Step-by-step explanation:
2 divided by 6 will give 0.3 in 1d.p
We will calculate this by using ratios and because these two triangles are similar, which is very important.
Explanation:
We see that the FG = 9 corresponds to the VU = 21. Therefore, FH = 18 corresponds to the UW = x.
9 : 21 = 18 : x
x = (21*18)/9
x = 378/9
x = 42.
The correct answer is B. 42.
