Section 1.
sin∠X =5/13
cos∠X =12/13
tan∠X = 5/12
Step-by-step explanation:
The sine of an angle is defined as; Opposite side/the Hypotenuse. From the right angle triangle given; the opposite side of angle X is 5 while the hypotenuse is 13.
The cosine of an angle is defined as; Adjacent side/Hypotenuse. From the right angle triangle given; the adjacent side of angle X is 12.
The tangent of an angle is defined as; Opposite side/Adjacent side.
Section 2
sin∠Y = 12/13
cos∠Y = 5/13
tan∠Y = 12/5
Step-by-step explanation:
The sine of an angle is defined as; Opposite side/the Hypotenuse. From the right angle triangle given; the opposite side of angle Y is 12 while the hypotenuse is 13.
The cosine of an angle is defined as; Adjacent side/Hypotenuse. From the right angle triangle given; the adjacent side of angle Y is 5.
The tangent of an angle is defined as; Opposite side/Adjacent side.
Section 3
The sin∠X and the cos∠Y are equal, their value is 5/13.
Step-by-step explanation:
The sine of angle is always equal to the cosine of its complement. Complement angles add up to 90 degrees. In this case, ∠X+∠Y =90 hence ∠X is a complement of ∠Y.
Section 4
The tangents of ∠X and ∠Y are reciprocals of each other. That is;
tan∠X = 5/12 and tan∠Y = 12/5. Clearly; tan∠Y = 1/tan∠X .
Step-by-step explanation:
The tangent of an angle will always be equal to the reciprocal of the tangent of its complement. In this case, ∠X+∠Y =90 hence ∠X is a complement of ∠Y.
