The radius of the circle below intersects the unit circle at (Three-fifths, four-fifths). What is the approximate value of Theta? A unit circle is shown. A radius with length 1 forms angle theta in quadrant 1. [Not drawn to scale] 0. 6 radians 1. 0 radians 36. 9 degrees 53. 1 degrees.

Sagot :

The measured value of Theta is  53.1 degrees.

Given

The radius of the circle below intersects the unit circle at (3/5, 4/5).

What is tan theta?

The measure of the tan angle is defined as the ratio of perpendicular by the base.

The measure of the tan theta is;

[tex]\rm Tan\theta=\dfrac{x}{y}[/tex]

Where the value of x is 3/5 and y is 4/5.

Substitute all the values in the formula

[tex]\rm Tan\theta=\dfrac{x}{y}\\\\\rm Tan\theta=\dfrac{\dfrac{4}{5}}{\dfrac{3}{5}}\\\\\\Tan\theta = \dfrac{4}{5} \times \dfrac{5}{3}\\\\Tan \theta=\dfrac{4}{3}\\\\\theta=tan{-1}(\dfrac{4}{3})\\\\\theta=53. 1 \ degrees\\\\[/tex]

Hence, the measured value of Theta is  53.1 degrees.
