Which side lengths form a right triangle?

B) 1, 8, √65

Step-by-step explanation:

For 3 side lengths to form a triangle the sum of two random sides must be bigger than the third side and their differences must be smaller than the third side.

1+8 > √65 because √65 is approximately 8.1

8-1 < √65

B. 1,8,(65)½

Step-by-step explanation:

For the side lengths to form a right triangle they have to obey the Phythagorean Theorem which when paraphrased says " the square of the longer side is equal to the sum of the squares of the other sides"

A . 2² + 15² = 4 + 225 = 229

17² = 289

Not a Phythagorean triple

B. 1² + 8² = 1 + 64 = 65

(65½)² = 65

A Phythagorean triple

C. 2² + (80½)² = 4 + 80 = 84

9² = 81

Not a Phythagorean triple.

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
