Angles θ and φ are angles in standard position such that: sinθ = -5/13 and θ terminates in Quadrant III

tanφ = -8/15 and φ terminates in Quadrant II

Find sin(θ + φ).

When terminates in quadrant III, both and are negative, and

When terminates in quadrant II, is negative and is positive, so

which gives

Now,

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

happy to

pls mark as brainliest.
