Mathematics

Answer:

x=30

Step-by-step explanation:

The two angles are on a straight line, so they are supplementary. They add to 180 degrees.

4x+20+40=180

Combine like terms

4x+60=180

Subtract 60 from both sides

4x+60-60=180-60

4x=120

Divide both sides y 4

4x/4=120/4

x=30

Answer:

30°

Step-by-step explanation:

The two angles: 4x + 20° and 40° are supplementary.

This means that when added, they will equal 180°. I know that these angles are supplementary because they form a straight line.

Let's write this as an equation:

4x +  20° + 40° = 180°

Solve:

4x + 20 + 40 = 180

Combine like terms (add 20 and 40):

4x + 20 + 40 = 180

4x + 60 = 180

Subtract 60 on both sides:

4x + 60 = 180

     -60     -60

4x = 120

Divide by 4 on both sides:

4x = 120

/4     /4

x = 30

Therefore, the value of x is 30 degrees.

What is the measure of c?<br> a = 15<br> j = 24<br> k = 32
inessss [21]

Answer:

The answer to your question is c = 20

Step-by-step explanation:

Data

a = 15

j = 24

k = 32

c = ?

Process

Use proportions to solve this problem. Compare the small triangle and the large triangle.

1.- Proportion of the small triangle

             c/15

2.- Proportion of the large triangle

            k/j

3.- Equal but terms and solve for c

            c/15 = k/j

-Substitution

            c / 15 = 32/24

            c = 32(15)/24

-Result

            c = 20

A hair dryer has a resistance of 11. 5. What current does it conduct when it is plugged into a wall outlet that provides 120 V?
Nata [24]

The current it conduct when it is plugged into a wall outlet that provides 120 V is 10.4A

<h3>Ohms law</h3>

The current passing through a conductor is proportional to the potential difference. Mathematically;

V = IR
where
V is the voltage = 120V

R is the resistance = 11.5 ohms

Required

Current I

Substitute

I = V/R
I = 120/11.5
I = 10.4A

Hence  the current it conduct when it is plugged into a wall outlet that provides 120 V is 10.4A
