Answer:

sinø = 1 /√5 ; cosø = 2 /√5 ; tanø = 1/2

Step-by-step explanation:

given sin ø + cos ø = 1.5

=>        sinø/cosø  +  cosø/cosø = 1.5

=>        tanø + 1 = 1.5

=>        tanø = 1.5 - 1 = 0.5 = 1/2

=>        tanø = 1/2

=>        opp/adj = 1/2  => opp = 1 units & adj = 2 units

therefore hypotenuse = √(1²+2²)  = √5  units

=> sinø = opp/hyp = 1 / √5

and cosø = adj/hyp = 2 / √5
