Katrina is launching a toy rocket.  For safety reasons, she stands 40 yards away from the rocket before it is launched.  He observes that the rocket hits its maximum height at an angle elevation of 42°.  What is the height the rocket reaches?  Round to the nearest tenth

We  can use the tangent to  solve  this

 

tan (42°)  = max height  / 40       multiply both sides by  40

 

40 * tan (42°)  =  max height  ≈  36  (yards)  = 108 ft
