In order to learn more about the answer, let's consider describing what the Tropic of Cancer is and what the Tropic of Capricorn is.

Tropic of Cancer- This is also known as "Northern Tropic." It is said that at the time of its naming, the sun was positioned in the <em>Cancer constellation </em>(one of the constellations of the zodiac). It is located at 23.5 degrees north of the equator and runs through the regions mentioned above.

Tropic of Capricorn-  This is also known as <em>"Southern Tropic."</em> It is said that at the time of its naming, the sun was positioned in the Capricorn constellation. It lies at 23.5 degrees south of the equator and runs through the regions mentioned above.

A circle with center P is shown. RS and ST are tangent to Circle P. What Is the degree measure of angle RST
LenaWriter [7]

Answer:

\angle RST =110

Explanation:

Given

\angle RPT = 70

See attachment

Required

Find \angle RST

To do this, we make use of the following theorem

\angle RST + \angle RPT = 180 --- angle at the center and angle between two tangents add up to 180 (i.e. they are supplementary angles)

So, we have:

\angle RST + 70 = 180

Collect like terms

\angle RST =- 70 + 180

\angle RST =110
