Answer:

92

Step-by-step explanation:

i will give you process,

x + 48° + 40° = 180° (being angle in a triangle)

or, x + 88° = 180°

or, x = 180° - 88° = 92°

Therefore, x = 92

Copy the same process

Answer:

57.2

Step-by-step explanation:

This is a right triangle so we can use trig ratios.

We are asked to find a side when we know a angle adjacent to that side. And we are given a side opposite of that angle. We can use Tangent to find the side length.

\tan(40)  =  \frac{48}{x}

Take the reciprocal of both sides.

\frac{1}{ \tan( 40) ) }  =  \frac{x}{ 48}

Multiply both sides by 48.

x =  \frac{1}{ \tan(40) }  \times 48

x = 57.2

Given the equation 6x + 18 = 72: Part A: Write a short word problem about a purchase made to illustrate the equation. (6 points)
bulgar [2K]

Considering the linear function 6x + 18 = 72, it is found that:

A. The problem is: You made a number of services for $6, plus a base pay of $18, and earned $72. How many services you made?

B. The solution is: x = 9.

C. In the context of this problem, the solution means that you made 9 services.

<h3>What is a linear function?</h3>

The general format of a linear function is presented as follows:

y = mx + b.

In which the coefficients are:

  • m is the slope, representing  the variable amount, that is, by how much y changes when x is increased by one.
  • b is the y-intercept, which is the fixed amount.

In this problem, the equation is:

6x + 18 = 72.

From the given equation, considering the slope of 6 and the intercept of 18, the problem can be presented as follows:

You made a number of services for $6, plus a base pay of $18, and earned $72. How many services you made?

The solution is found isolating the variable x, as follows:

6x = 72 - 18

6x = 54

x = 54/6

x = 9.

The solution x = 9 represents the number of services that you made, in the context of this problem.
