In ΔUVW, w = 840 cm, u = 350 cm and ∠V=63°. Find the area of ΔUVW, to the nearest square centimeter.

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

a negative exponent is translated as follows:

so, we have

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify
