The area of a traingle is

So we need to know the base and the height
To work out the sides of a right angle triangle we can use a²+b²=c
c is the hypotenuse and a and b are the other sides
Because this triangle is isoceles we know that a and b are the same
a²+b²=c²
a²+a²=c²
2a²=c²
2a²=(x√6)²
2a²=(x√6)(x√6)
2a²=x²+x√6+x√6+6
2a²=x²+x√6+x√6+6

Answer:
421.4 miles
Step-by-step explanation:
The flight legs are orthogonal, so the distance can be found using the Pythagorean theorem:
1.2 h × 120 mph = 144 mi
3.3 h × 120 mph = 396 mi
The distance at the end of the second flight leg is ...
d = √(144² +396²) = √177552 ≈ 421.37
The plane is about 421.4 miles from its starting point.
_____
The heading to its end point is 20° +arctan(3.3/1.2) ≈ 90.02°.
