Which side lengths form a right triangle? choose all answers that apply: choose all answers that apply: (choice a) a \sqrt4, 10, 116 4 ? ,10,116 (choice b) b 3, 6, 83,6,8 (choice c) c 30, 40, 5030,40,50

(C)      

Step-by-step explanation:

In order to find whether the given side lengths form a right triangle or not, we must show that it satisfies the Pythagoras theorem.

A. , 10 and 116

According to Pythagoras theorem,

⇒

⇒

which does not satisfy the condition, therefore these side lengths do not form a right triangle.

B. 3,6 and 8

According to Pythagoras theorem,

⇒

⇒

⇒

which does not satisfy the condition, therefore these side lengths do not form a right triangle.

C. 30, 40 and 50

According to Pythagoras theorem,

⇒

⇒

⇒

which satisfies the condition, therefore theses side lengths form right triangle.

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
