On a unit circle, the terminal point of 0 is (sqrt3/2,1/2)<br><br> What is 0?
san4es73 [151]

Answer:

The measure of \theta is 30°.

Step-by-step explanation:

In the statement, the angle has been misrepresented. The corrected statement is described below:

<em>"On a unit circle, the terminal point of </em>\theta<em> is </em>\left(\frac{\sqrt{3}}{2}, \frac{1}{2}  \right)<em>. What is </em>\theta<em>?"</em>

The measure of the angle (\theta), in radians, is in standard form, that is, it is done with respect to the +x semiaxis. The measure of the angle whose terminal point is of the form (x,y) is determined by the following inverse trigonometric function:

\theta = \tan^{-1}\left(\frac{y}{x} \right) (1)

If we know that x = \frac{\sqrt{3}}{2} and y = \frac{1}{2}, then the measure of \theta is:

\theta = \tan^{-1} \frac{\sqrt{3}}{3}

\theta = 30^{\circ}

The measure of \theta is 30°.

Given: △KLM, LM=20 3 <br> m∠L=105°, m∠M=30°<br> Find: KL and KM
Yuki888 [10]

Answer:


Step-by-step explanation:

Split the triangle into a 30-60-90 triangle. Since you have LM from that triangle, you can figure out the other sides. Then, using the leg from that triangle, the one next to it is a 45-45-90 triangle, meaning it's isosceles.

KM = 30 + 10√3

KL = 10√6
