Which statements are true about the tangent function? check all that apply
1. tan(∠pab) = y/x
2.tan(∠apb) = x/y
3.tan(∠pab) = sin(< pab)/cos(< pab)
4.tan(∠pab) = cos(< pab)/sin(< pab)
5.tan(∠pab) = pb/ab

Function tangent of an angle in a right triangle equals
- opposite side / adjacent side
- sine of the angle / cosine of the angle

For this reason, all answers choices are correct except the fourth one, which is the cotangent of angle PAB.

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's
