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
