For A the answer is 85% correct. Then 15% incorrect. I got the number correct by taking 68 and dividing by 80. To get the number incorrect I took the 15 other questions (80-68) and did 12 divided by 80 to get the 15% incorrect.

Determine if the following triangle is a right triangle or not using the Pythagorean Theorem Converse. Triangle with side length
Nadusha1986 [10]

Answer:

It is a right triangle

Step-by-step explanation:

Information needed:

Formula: a^2+b^2= c^2

b: leg

c: hypotenuse

the longest side is always the hypotenuse, so 17 in

the order of legs don't matter so 8 in and 15 in

Solve:

a^2+b^2= c^2

8^2+15^2= 17^2

64+225= 289

289= 289

Final answer:

It is a right triangle
