Select the correct answer Lucy started the proof of the law of cosines using triangle WXY as shown
w
w
Z
Given XZIWY AWXZ and AYXZ are right triangles
Step 1: Cos(W) = W2; ycos(W) = w z
Step 2: sin(W) = XE; XZsin(W)=y
Step 3: ZY = =-ycos(W)
step 4: W2 = (x-ycos(W))2 + x 22
Which step contains the first error in calculation?

b

step-by-step explanation:

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)

range =5

step-by-step explanation:

to find the range, we take the largest value and subtract the smallest value.

the largest value is 5

the smallest value is 0

the range is 5-0   =5

one peck is 9.309 quarts
