Can someone please help me I been waiting for a long time. NO LINKS PLEASE, I just need help because if someone doesn't help me I will be sad :/

x= about 56 degrees

Step-by-step explanation:

solve the triangle

solve for the third side

Hope this helps UwU

x = 66.4

Explanation in word form:

Since we are given two sides of said triangle, the adjacent side (5-3) and the hypotenuse (9-4), we must do the cosine function. First, we should solve the expressions of each side, this results in the adjacent side being (2) and the hypotenuse being (5). After this, we can plug each into the inverse cosine function. After (cos^-1) = (2/5), we receive 66.4218, rounded to the nearest tenth would be 66.4 (after rounding down).

In step-by-step form:

1) Identify the two sides given: adjacent (5-3) and hypotenuse (9-4).

2) Simplify said sides: adjacent (2) and hypotenuse (5).

3) Plug each of those into the inverted cosine (cos) function: (cos^-1 = 2/5)

4) Simplify said equation, you should receive the answer of 66.4218.

5) Round 66.4218 down, ending up with 66.4.

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.

could u provide us some answer choices or hmm idk maybe a table for us to anser with ? ?
