OBTUSE

Step-by-step explanation:

We can determine this based on the the pythagorean theorem!

With Pythagorean Theorem, c is the longest length in the triangle... So, if c = a squared plus b squared, then it is a right triangle! If c is less, it is acute, and finally, if C is more than the two - then it is obtuse!

So let's see...

This is an OBTUSE triangle, since c adds up to be more than a and b.

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
