A student begins a proof law of cosines. His work is shown. The next step in the proof is to write an expression for the length of side AZ in terms of _
Options are A. y, z and x. B. x, z and z. C. y, z and y.

Then the student should write an expression for the length of side AY in terms of _
Options are A. z and y, B. x and z, C. z and y.

Next he can use the_
Options are A. Laws of sines, B. Pythagorean theorem, or C. Tangent function.

To relate x, y,z and _
Options are A. x, B. y, C. z

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.

step-by-step explanation:

for a it would be 24 children.

for b i don't understand the question. is it saying for each individual person they pick 5 reds to 7 greens or is it the whole group. clarify and i hope this can you.

step-by-step explanation:

66.666666667%

step-by-step explanation:

divide 150 by 100

divide 100 by 1.5

there you go!

decreased by 33.333333334%
