How do you solve for the Rations of Special Triangles? This is confusing

The answer to your question is  x =

Step-by-step explanation:

Data

right triangle

x = ?

hypotenuse = 3

To solve this problem use trigonometric functions. The trigonometric function that relates the opposite side and the hypotenuse is sine.

            sin Ф = Opposite side / hypotenuse

-Solve for Opposite side (x)

            x = hypotenuse  sin 45

-Substitution

 sin 45 =

            x = 3

-Solution

            x =  It is not possible to simplify any more.

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d
