Which trig ratio should you use to find the given side?
Sine
Tangent
Cosine

a. sine

Step-by-step explanation:

As it can be seen from the figure, triangle ABC is the right-angled triangle with Angle C is equal to 90 degree.

In a right-angled triangle, there is a formula as following:

+) sine (an acute angle) = (length of its opposite side)/ hypotenuse

In the figure, angle B and length of the hypotenuse are given.

As x is the length of AC and AC is the opposite side to angle B

=> So that we can use sine to find x

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680

i think asking google will you get the answer to that question
