Asked by Ian

Use trig to find a side. Solve for x. Round to the nearest tenth, if necessary. IJ number is x. KJ number is 21. What is the number for IK. The angle for this triangle is 56.

Assuming this is a right triangle with right angle at I and KJ = 21 is the hypotenuse, angle at J = 56°.

- IJ = x = KJ·cos(56°) = 21·cos56° ≈ 21·0.5592 ≈ 11.7
- IK = KJ·sin(56°) = 21·sin56° ≈ 21·0.8290 ≈ 17.4

So IJ ≈ 11.7 and IK ≈ 17.4 (to the nearest tenth).
