If the sin 60 agrees equals the square root of three over two which statement is true

torisob [31]

Given that
$\sin60^o= \frac{ \sqrt{3} }{2}$

$\cos 30^o =\sin(90-30)^o=\sin60^o=\frac{ \sqrt{3} }{2}$ ,

$\cos 120^o =-\sin(180-120)^o=-\sin60^o=-\frac{ \sqrt{3} }{2}$ ,

$\cos30^o\neq0$ ,

$\cos120^o\neq0$

Therefore, the true statement is
$\cos 30^o =\sin(90-30)^o=\sin60^o=\frac{ \sqrt{3} }{2}$ ,
because the cosine and sine are complements.

What is the measure of m? 6 3 n 18 m = [?] Give your answer in simplest form. Enter

alina1380 [7]

By solving a system of equations, we will see that m measures 12 units.

<h3>How to get the measure of m?</h3>

Notice that we have 3 right triangles.

Then we can write the equations:

cos(a) = 6/m

For the small triangle on the left, where m is the hypotenuse.

cos(a) = m/(6 + 18)

For the larger triangle (the one composed of the two triangles).

Where in both equations, angle "a" is the one in the top left.

Then we have the system of equations:

cos(a) = 6/m

cos(a) = m/(6 + 18)

Then we can write:

6/m = m/(6 + 18)

If we simplify the expression, we get:

6*(6 + 18) = m^2

6*(24) = m^2

144 = m^2

√144 = m = 12

Then we conclude that m measures 12 units.

Teresa is factoring this polynomial by grouping. Which common factors should be used in the next step of factoring? 10x3+3x2−20x

Basile [38]

Answer:

The common factors should be used in the next step of factoring is x² and -2.

Step-by-step explanation:

Consider the provided expression.

$10x^3+3x^2-20x-6$

Factor the above expression by grouping.

$(10x^3 + 3x^2) + (-20x -6)$

Factor out x² form the first parentheses and -2 from the second parentheses.

$x^2(10x+3) -2 (10x+3)$

Hence, the common factors should be used in the next step of factoring is x² and -2.
