Find the exact values of sin a and cos a. write fractions in lowest terms. (5 points) a right triangle abc is shown. leg ac has length 33, leg bc has length 44, and hypotenuse ab has length 55.

sin a = four fifths ; cos a = three fifths
sin a = three fifths ; cos a = four fifths
sin a = five fourths ; cos a = five thirds
sin a = four thirds ; cos a = three fourths

Solution:

Given a right triangle ABC

The figure is attached below

From given,

AC = Base = 33

BC = Perpendicular = 44

AB = hyptotenuse = 55

We know that,

Also,

Thus the values are found

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
