The coordinates g(7,3), h(9, 0), (5, -1) form what type of polygon? an obtuse triangle an acute triangle o an equilateral triangle a right triangle

Is an acute triangle

Step-by-step explanation:

we know that

the formula to calculate the distance between two points is equal to

we have

G(7,3), H(9, 0), I(5, -1)

step 1

Find the distance GH

substitute in the formula

step 2

Find the distance IH

substitute in the formula

step 3

Find the distance GI

substitute in the formula

step 4

Verify what type of triangle is the polygon

we know that

If applying the Pythagoras Theorem

----> is a right triangle

----> is an obtuse triangle

----> is an acute triangle

where

c is the greater side

we have

substitute

therefore

Is an acute triangle

what i would say the best answer is a. 40.5
