(I really need help on this) FGHIJ ~ YUVWX. Find UY and GH.
Sveta_85 [38]

Answer:

UY = 90

GH = 4

Step-by-step explanation:

Since both figures are similar, the ratio of their corresponding side lengths would be the same.

Thus:

✔️UY/GF = XW/IJ

UY/10 = 54/6 (Substitution)

Multiply both side by 10

UY = (54*10)/6

UY = 90

✔️Also,

UV/GH = XW/IJ

36/GH = 54/6

36/GH = 9

GH = 36/9

GH = 4

The answer is 100X because if you do 5x-4x first it will be 1x. Later on, if you do the exponent you have 1x times 1x. Then you do 1x+9x = 10x

Then you do 10x times 10x because of the exponent is telling you how times you do it and it equals to 100x.

Answer= 100x



I hope this helps YOU!
