Which set of side lengths form a right triangle? a 14m, 20m,25m b 10cm, 6cm,8cm c 7cm, 8cm, 10cm d 3ft, 6ft, 5 ft

If you have a right triangle, you can use the Pythagorean theorem, which is a²+b²=c². (c is the longest side or the hypotenuse)

You plug in the shorter sides for a and b, then you square root the answer.

A 14m, 20m, 25m

14² + 20² = 25²

196 + 400 = 625

596 = 625 X

B 10cm, 6cm, 8cm

6²+8²=10²

36+64=100

100=100 So your answer is B

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.

a

step-by-step explanation:

the denominator cannot be the same as one of the factors.

8 denominator times 2 denominator = 16

and 7 numerator time 11 = 77

77/16= 77/16 ( they cannot be further simplified)
