The measures of the angle of a triangle are shown on the figure below. Solve for X.

Answers

Internal angles sum: 180(sides-2) = 180

5x = 180 - (48 + 90 + 17)

x = 25/5

x = 5

answer: 5

proof:

(90 + 48) + (5(5)+17) = 180

Answer:

x=5

Step-by-step explanation:

We know that a triangle consists of 180°. So to start, you take the two given angles and add them together. 48+90=138.

Now you subtract the 138 from the total of 180 to get the degrees of the remaining angle. 180-138=42°.

Now set the unknown angle equal to 42. (5x+17) = 42

Subtract 17from both sides to get 5x=25

Divide 5 from both sides to get x=5

Answer and Step-by-step explanation:

We are told that there is 24 cupcakes, which total up to be 36 dollars.

c will represent One cupcake.

We would do 36 divided by 24 to find the cost of One cupcake.

[tex]\frac{36}{24} = \frac{3}{2} = 1.5[/tex]

Each cupcake (c) is equal to $1.5.

Equations that would get us to this would be:

36/24 = c

Answer:

Step-by-step explanation:

x = 12

the triangle was made smaller (i forget what the term is)

it was made smaller by  [tex]1\frac{1}{3}[/tex]

to find that you divide 24 by its equivalent side on the other triangle which would be 18

24 / 18 =  [tex]1\frac{1}{3}[/tex]

to find what x is equal to you have to find the equivalent side on the other triangle. this would be 16. since the triangle with 16 is bigger the equation is:

16 / [tex]1\frac{1}{3}[/tex] = 12

so x = 12

The distance from Cherotich's home to school is
2km 400m. He goes to school in the morning
and returns in the evening daily. What distance
does he cover from Monday to Friday?

Answers

Answer:

24 kilometers

Step-by-step explanation:

Given

Represent the distance with x

[tex]x = 2km\ 400m[/tex]

Required

The distance covered for 5 days (i.e. Monday to Friday)

First, we calculate the distance covered in a day

He covers the same distance when going to school and when coming back from school.

So, the daily distance is:

[tex]Daily = 2 * x[/tex]

[tex]Daily = 2 * (2km\ 400m)[/tex]

[tex]Daily = 4km\ 800m[/tex]

In 5 days, he covers:

[tex]5\ days = 5 * Daily[/tex]

[tex]5\ days = 5 * (4km\ 800m)[/tex]

[tex]5\ days = 5 * (4km+ 800m)[/tex]

Open bracket

[tex]5\ days = 5 * 4km+ 5 * 800m[/tex]

[tex]5\ days = 20km+ 4000m[/tex]

Convert m to km

[tex]5\ days = 20km+ 4km[/tex]

[tex]5\ days = 24km[/tex]

Step-by-step explanation:

This question asks us to estimate the amount of money Paul gave to Charity.  

To work out an estimate we must start by rounding the numbers we are given to 1 significant figure and the

Starting with 19.95 --> this rounds to 20 and 395 rounds to 400.  

Then we have to multiply these numbers together:

8000-6000=2000

The answer is 2000.

Answer:

x = 119

z = 28

Step-by-step explanation:

To find x: Because of same-side exterior angles, you can add x and 61 together to find 180 degrees.

x + 61 = 180

Subtraction: x = 119

To find z: Use given quantities, not found variables for most accurate answer. Because of opposite exterior angles, you can equal them to each other.

61 = 5z - 79

Addition: 140 = 5z

Division: 140/5 = 5z/5

Final Answer = 28 = z

X = 19
Z = 28
