The answer should be the third one I believe
Answer:
2.0806 × 10²
Step-by-step explanation:
The slope is -2/3 or -2 over 3
STR is a triangle as shown in the picture. If Luke decided to subtract 128º from 180º, that's because he understood that the sum of the internal angles in a triangle is 180º, and therefore the angles RST and TRS together make 128º.
As a result, RST will be
128º - TRS
where TRS is the angle at R, as shown in the picture
