Question 1204577
<br>
(1) Determine that angle K in triangle IKL is 180-(60+25) = 95 degrees.<br>
(2) Use the law of sines to find IK:<br>
{{{IK/sin(25)=400/sin(95)}}}<br>
(3) Use tangent = opposite/adjacent in right triangle IJK to find JK:<br>
{{{JK/IK=tan(38)}}}<br>
You don't learn anything by having me do the calculations for you; I leave them to you.<br>
Your answer should be 132.6 to one decimal place.<br>
