- obtuse
- right
- not a triangle

9514 1404 393

  right

Step-by-step explanation:

You should recognize that (5, 12, 13) is a Pythagorean triple, so are the lengths of sides of a right triangle.

__

In any event, you can check to see.

  5² +12² = 25 +144 = 169 = 13²

The side lengths satisfy the Pythagorean theorem, so correspond to sides of a right triangle.

Some Pythagorean triples commonly seen in algebra, geometry, and trig problems are ...

  (3, 4, 5), (5, 12, 13), (7, 24, 25), (8, 15, 17), (9, 40, 41)

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
