The line has a positive slope of [2.5 - 1.5]/[5-3] =1/2. The the angle of lean is 26.6°.
The answer would be letter A
(2/5) / (9/1)
Flip second fraction and multiply instead of divide
(2/5) * (1/9)
= 2/45
Answer:
R___S___T
RT=RS+ST
39 = (23 - 2x) + (9x - 5)
39 =7x + 18
7x = 39 - 18
7x = 26
x = 26/7
x= 3.7
RS= 23 - 2x = 23 - 2(3.7) = 23 - 7.4 = 15.6
If went ST = 9x -5 = 9(3.7)- 5 = 33.3 - 5 = 28.3
I hope I helped you^_^
