Find the length of the missing side. if necessary, round to the nearest tenth.
a) 75
b) 37.5
c) 19.4
d) 53.2

The pythagorean theorem states that the sum of the squares of two legs of a right triangle is equivalent to the hypotenuse.

So:

35^2 + b^2 = 40^2

1225 + b^2 = 1600

b^2 = 375

b =

b = 19.3649

The missing side's length rounded to the nearest tenth is Option C, 19.4

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
