IrinaVladis [17]
█ Explanation <span>█

Let's call the missing altitude 'x'. 

</span><span>✦ To find the plane's altitude, find the tan of 30 degrees. The side opposite is going to be x, while the side adjacent is going to be 4.4 miles. 
</span>✦ Tan(30)= \frac{x}{4.4}
✦ 5.7735= \frac{x}{4.4}
✦ x=4.4*.57735
✦ x=4.4*.55735
✦ x=2.54 mi
<span>✦ We usually write altitude in feet.
