Question

In RST, R = 23* and S = 136*. Which list has the sides of RST in order from shortest to longest?

RS, TR, ST

TR, ST, RS

ST, RS, TR

ST, TR, RS

TR, RS, ST

RS, ST, TR

Answer 1

RS,ST,TR IS THE ANSWER

Answer 2

• RS, ST, TR

Explanation:

The third angle measures:

• T = 180° - (136° + 23°) = 21°

Angles and opposite sides are:

• S = 136° → TR
• R = 23° → ST
• T = 21° → RS

The greater the angle, the greater the opposite side, therefore the sides in increasing order will be:

• RS, ST, TR
