Answer:

Step-by-step explanation:

Given that a student's work to distribute and simplify a radical is shown below.

Given

(-5√20+√3)*(2+√3)

The next step of distribution is

-5√60+2√3+√9 is done correctly.

Next step is

-40√5-20√15+2√3+3

I term = -10√20=-20√5

Correct answer is

Hence c) the student did not properly simplify all radicals

Which property can be justified using the ratios in triangle XYZ ?
Alenkasestr [34]
The correct answer is B.

Determine and recall first the trigonometric functions:

Sin A = Opposite/Hypotenuse
Cos A = Adjacent/Hypotenuse
Tangent = Opposite/Adjacent

If for example we try to take an angle, for example the Y, then Y is opposite Y. The Hypotenuse will be the longer side which is going to denoted by X and the next side will be Adjacent which will be denoted by Z. 

Use this test to answer:

Sin Y = Y/X

where:

Y = opposite
X = hypotenuse 

Cos (90 - y) = cos (90 - 50) = cos 40

where Z = 40
we look for cos Z = Y/X

Therefore,

Sin Y = Cos (90 - Y)
