Question

5. Find JK to the nearest whole number. A

Answer 1

Answer:

Sin(x) = Opposite ÷ Hypotenuse

Sin(44) = JK ÷ 90

0.6946583705 = JK ÷ 90

0.6946583705 × 90 = JK

JK = 62.5192533413

Rounding JK to the nearest whole number:

JK = 63

Answer 2

Answer:

JK ≈ 63 units

Step-by-step explanation:

Using the sine ratio in the right triangle

sin44° = $\frac{opposite}{hypotenuse}$ = $\frac{JK}{JL}$ = $\frac{JK}{90}$ ( multiply both sides by 90 )

90 × sin44° = JK , that is

JK ≈ 63 ( to the nearest whole number )
