Can someone help me figure out x?

Given:

Given that ABC is a right angled triangle.

The length of AB is 29 units.

Length of BC is 9 units.

The measure of ∠A is x.

We need to determine the value of x.

Value of x:

The value of x can be determined by using the trigonometric ratios.

Thus, we have;

Substituting the values, we get;

Simplifying, we get;

Taking on both sides, we get;

Thus, the value of x is 18.08

Hence, the measure of ∠A is 18.08°

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
