Answer:
Alright in this problem we have a right triangle and it tells us that the high pontoon you, so here's the right angle, The high panis is 78 centimeters. Um and then it tells us that the one of the shorter sides is 2.1 cm and we need to find this other side. Um So for this one, just need to do the pythagorean theorem. So x squared plus 2.1 squared equals 7.8 squared. Um So x squared is gonna equal 7.8 Squared -2.1 Squared. And then when you pull out your calculator, figure all that out. 7.8 squared 60.84 2.1 sq is 441. Uh Subtracting those, oh Is 56.43. So X squared is going to equal that. So then we just got to take the square root Of both sides. So X. You're missing side is going to be 7.511 9904 15 is what I got on my calculator. I don't know how far they where they want you around the answer. Um So so there you go. That's how you find the missing side of that, of this right triangle
