$\frac{sin( x)}{ \sqrt{1- (sin(x))^{2} } } = \frac{sin (x)}{ \sqrt{ (cos(x))^{2} } } = \frac{sinx}{cos x} =tan (x)$

Answer with explanation:

In the problem ,theta is replaced by A.

Use the following trigonometric identity to solve the problem

$1.sin^2A+cos^2A=1\\\\2.tan A=\frac{sinA}{cosA}$

The Given function is

$\frac{sin A}{\sqrt{1-sin^2A}}\\\\= \frac{sinA}{\sqrt{cos^2A}}\\\\=\frac{sinA}{cosA}\\\\=tan A$

Yo sup??

We can solve this problem by applying trigonometric ratios.

sin36=XY/WY

WY=5/sin36

=8.5

Hope this helps.

The highest score of the women’s basketball championship was Jessica Bradley. She scored 147 more points and Tina Hardtner her t

Rufina [12.5K]

Answer:

MAKE MY ANSWER BRILLINEST PLEASE:)

Step-by-step explanation:

LET:

j = the points that Jessica scored

t = the points that Tina scored

Jessica scored 147 more points than Tina:

j = t + 1497

Together, Bradley and Harner scored 1601 points:

j + t = 1601

by solving the system of equations:

j = t + 147

j + t = 1601

we find

j = 856 points

t = 707 points

Jessica Bradley scored 856 point.

Tina Harner scored 707 points.

Answer:

m∠y=72°

Step-by-step explanation:

<u><em>The question is</em></u>

Find the measure of angle y

step 1

Find the measure of angle x

see the attached figure to better understand the problem

we know that

m∠x=67° -----> by corresponding angles

step 2

Find the measure of angle y

we know that

(m∠x+m∠y)+42°=180° -----> because form a straight line

substitute the measure of angle x

67°+m∠y+42°=180

m∠y+108°=180

m∠y=180°-108°

m∠y=72°

What is the argument of -5\sqrt{3}+ 5i?

Shtirlitz [24]

Answer:

150 degrees

Step-by-step explanation:

Graphing the complex number we see the angle terminates in the second quadrant. This means the argument, the angle, will be between 90 degrees and 180 degrees.

So if we create a right triangle with that point after graphing it. We see the height of that triangle is 5 because that is the imaginary part. The base of that triangle has length $5\sqrt{3}$ . The problem is this doesn't give us any part of the angle we want, but it does give us the complementary of the part of the angle that is in second quadrant.
