Which triangle is similar to △ABC if sin(A) = One-fourth, cos(A) = StartFraction StartRoot 15 EndRoot Over 4 EndFraction, and ta
n(A) = StartFraction 1 Over StartRoot 15 EndRoot EndFraction? Triangle R S T is shown. Angle R S T is a right angle. The length of hypotenuse R T is 13, the length of S T is 12, and the length of R S is 5. Triangle I J K is shown. Angle I J K is a right angle. The length of hypotenuse I K is 3 StartRoot 15 EndRoot, the length of J K is 3, and the length of J I is 12. Triangle M L N is shown. Angle M N L is a right angle. The length of hypotenuse L M is StartRoot 15 EndRoot, the length of M N is 3, and the length of L N is StartRoot 6 EndRoot. Triangle X Y Z is shown. Angle Y Z X is a right angle. The length of hypotenuse X Y is 24, the length of X Z is 6 StartRoot 15 EndRoot, and the length of Z Y is 6.
(2,-5) move up three steps is (2, -2). if you draw it on a paper(and draw lines to connect them), you can see that they form a right triangle. apply a²+b²=c² and you should get 3²+2²=(√13)²
