Find the value of x. If necessary, round your answer to the nearest tenth. FG¯¯¯¯¯¯¯¯⊥OP¯¯¯¯¯¯¯¯,RS¯¯¯¯¯¯¯⊥OQ¯ ¯¯¯¯¯¯¯, FG = 20, RS = 20, OR = 15

i wish i could you, i have no idea how to answer this

step-by-step explanation:

answer: 4  

the square root of 16 is 4. it is a very simple mathematic concept. a square root when a number multiplied by itself will result in a number. here, the number 16 comes when 4 is multiplied by 4. hence the square root of 16 is 4. you can always figure out a square root by the inverse operation of squaring.  

measurement of the swimming pool is given as = 7 yards 4.79 feet

first we will convert this to yards only.

1 foot = 0.33 yards

so, 4.79 feet = yards

so total yards are = yards

now we will convert this in meters.

1 yard = 0.914 meters

8.580 yards = meters

0.842 m = 0.842*100 = 84.2 cm

this becomes 7 meters and 84.2 cm

hence, the pool is 7 meters and 84.2 cm wide.
