3/5 HELP! Find the missing side. Round to the nearest tenth

Mathematics
1 answer:
qaws [65]2 years ago
6 0

The missing side of length x is 15 units after using the cos ratio in the right angle triangle.

<h3>What is trigonometry?</h3>

The branch of mathematics deals with the relations of the sides and angles of triangles and with the relevant functions of any angles.

Also, mathematics is concerned with specific functions of angles and their application to calculations.

There are six functions of an angle commonly used in trigonometry.

Their names and abbreviations are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (cosec).

Given that:

The right-angle triangle has one side given and one angle given.

Bye the use of trigonometry, we have

Cos Ф = Base/Hypotenuse

Base = x units

Hypotenuse= 17 units

Cos 26°= x units/17 units

x =17* Cos 26°

x=15.27 units ≈ 15 units

Therefore, the missing side of length x is 15 units.

Graph the equation on the coordinate plane. y=x-3 Select two points on the line to graph the line.​
yawa3891 [41]

The slope of a line is used to determine its steepness of a line.

What is the standard form of an equation?

One way of expressing linear equations is in their standard form. There are several ways to express a linear equation, including the standard form, the slope-intercept form, and the point-slope form. The general form of a linear equation, commonly referred to as the standard form, is written as Y = MX + C; A linear equation or one-degree equation is one in which the maximum power of the variable is 1. For instance, the equation 4x + y = 6 is linear since the maximum power of both x and y is 1. The equation in its standard form is written as Ax + By = C, where A, B, and C are all integers and x and y are the variables.

The standard formula for finding the equation of a line is expressed as:

y = mx + b

m is the slope

b is the y-intercept

Given the equation:

y = x -3;

The slope of the graph will be 1 with no y-intercept.

The slope of a line is used to determine its steepness of a line.

So, substituting the value of x as 0;

So, The value of y will be -3;

That is: (x,y) = (0,-3);

Now, substituting x =1;

So, The value of y will be: -2;

That is: (x,y) = (1,-2);

Hence,

The slope of a line is used to determine its steepness of a line.
