Point A altimeter reading: +450
Point B altimeter reading: -50
No, the Pythgorean Theorem only applies to right triangles. To get two right triangles, you divide a rectangle diagonally. Dividing a hexagon into two pieces produces trapezoids or pentagons depending where it is divided.
I don't have my calculator handy just now. But just looking at that problem, why don't you try +20 and -45 and see if they do the job.
0.06 or you can just put 6.
Basically, you have to multiply 30% x 20.
Glad I could help☺️
