c=\sqrt{16 ^{2} + 4^{2} } =16.4924
which is approximately 16.5
for the second question
we also use Pythagoras

students were asked to simplify the expression . two students' work is given. student a step 1: step 2: step 3: 1 tan2 θ step 4:
Whitepunk [10]

Student B is wrong , student A is correct in simplifying the expression .

Expression B must be simplified to cot θ .

Formulas to be used are :

1 - sin^{2} θ = cos^{2}θ

 1 - cot^{2}θ = tan^{2}θ .

Since , location of error is step 3 , we will start from there

[ ( 1 - sin^{2}θ ) / sin θ ] / cos θ    = [ ( 1 - sin^{2}θ ) / sin θ ] * [ 1 / cos θ ]

                          = ( 1 - sin^{2}θ ) / ( sin θ * cos θ )

               = cos^{2} θ / ( sin θ * cos θ )

                   = cot θ .

What is 3 1/8 - 1/2
irina1246 [14]

Answer:

\frac{21}{8}

Step-by-step explanation:

Given: 3\frac{1}{8} - \frac{1}{2}

Let's changed that mixed number to an improper fraction. Now we get:

\frac{25}{8} - \frac{1}{2}

Let's find out least common denominator. This one is easy, the LCD is 8. Now that we know the LCD, let's convert both our fractions:

\frac{25}{8} - \frac{4}{8}

We can use \frac{4}{8} because it is equal to \frac{1}{2}. Now, all we need to do is subtract the numerators:

\frac{25}{8} - \frac{4}{8}=\frac{21}{8}
