Find the value of x PLEASE EXPLAIN

Mathematics
2 answers:
dedylja [7]2 years ago

We can say that:

  • In the first triangle, x = 57°
  • In the second triangle, x = 111°

<h2>Let's go!</h2>

We must know that the sum of all the internal angles of a triangle is equal to 180°. So, just solve an equation to determine x in each triangle.

<h3>First triangle:</h3>
  • 67 + 56 + x = 180 → Sum:
  • 123 + x = 180 → We move 123 to the other side, changing its signal.
  • x = 180 - 123 → Subtract:
  • <u>x = 57°</u>
<h3>Second triangle:</h3>
  • 22 + 47 + x = 180 → Sum:
  • 69 + x = 180 → We move 69 to the other side, changing its signal.
  • x = 180 - 69 → Subtract:
  • <u>x = 111°</u>

<u>________________</u>

<em>Hope this helps! Good studies! </em>☺

Answer:

x = 57, x = 111

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles and equate to 180, that is

x + 67 + 56 = 180

x + 123 = 180 ( subtract 123 from both sides )

x = 57

---------------------------------------------------------------------

Similarly

x + 47 + 22 = 180

x + 69 = 180 ( subtract 69 from both sides )

x = 111

Eli and Samantha work at a dry cleaners ironing shirts. Eli can iron 20 shirts per hour, and Samantha can iron 35 shirts per hou
MrRa [10]

Answer:

see the explanation

Step-by-step explanation:

Let

x ----> the number of hours Eli worked

y ----> the number of hours Samantha worked

we know that

Eli and they ironed 400 shirts between them

so

 ----> equation A

Samantha worked 2 more hours than Eli

so

----> equation B

solve the system by substitution

substitute equation B in equation A

solve for x

Find the value of y

substitute the value of x in equation B

therefore

The number of hours Eli worked was 6 and the number of hours Samantha worked was 8

*<br> Find the area of a triangle: Base of 8 cm Hight of 9 cm
Sliva [168]

Answer:

36 cm

Step-by-step explanation:

The formula to find the area of a triangle is A=1/2bh where b stands for base and h for height.

So, 8 times 9 equals 72, and 72 divided by 2 is 36.

The path a character takes to navigate a level of a video game is given in the following graph.
KonstantinChe [14]

We want to find the domain for the graphed function. We will see that the correct option is A: -12 ≤ x ≤ 14

<h3>What is the domain of a function?</h3>

For a function f(x) we define the domain as the set of possible inputs that we can use in the function.

In this case, we need to see the values in the horizontal axis that the graph covers.

We can see that it goes from -12 to 14. We also can see that there are two jumps, at x = -6 and at x = 8, but these values belong to the graph (denoted by the black dot) meaning that these are in the domain.

Then the domain is:

-12 ≤ x ≤ 14
