What relationship do the ratios of sin x° and cos y° share?

Step-by-step explanation:

Step 1:  Find sin of x

Step 2:  Find cos y

Step 3:  Find the relationship

Since sin(x) = 12/13 and cos(y) = 12/13, we can assume that sin(x) = cos(y)

 sin(x) = cos(y)

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°

hope this
