Answer:
Part A)
Part B)
Part C)
Step-by-step explanation:
Part A) we know that
In the right triangle ABC of the figure the sine of angle A is equal to divide the opposite side angle A by the hypotenuse
so
substitute the values
Part B) we know that
In the right triangle ABC of the figure the cosine of angle A is equal to divide the adjacent side angle A by the hypotenuse
so
substitute the values
Part C) we know that
In the right triangle ABC of the figure the tangent of angle A is equal to divide the opposite side angle A by the adjacent side angle A
so
substitute the values
The correct answer is 42x^4-24x^3+12x^2
Answer:
12.2*1=12.2
12.2*0.45=5.49
5.49+12.2=17.69
Step-by-step explanation:
