Find the value of x. DO NOT SEND ME A LINK LIKE THIS tnylnk.gq/7Hrq

Mathematics

Answer:

30

Step-by-step explanation:

Remark

The angle that looks like a shark's fin sticking out of the water is also 75o.  So you have 2 angles that are 75 degrees each. Add them together.

Solution

x + 75 + 75 = 180            All triangles have 180 degrees.

x + 150 = 180                  Subtract 150 from both sides.

x= 180 - 150

x = 30

Answer:

30

Step-by-step explanation:

since the 2 sides are congruent, the two angles are congruent, so

75+75+ x= 180

150+x=180

x=30

Answer:

x = 14

y = 4

Explanation:

Ok so, just from looking at the two triangles i can tell they're congruent right triangles. I used different colors to show which sides of the triangle correspond and are equal to each other in my attatched photo.

So the side thats equal to x is the same length as the side that's equal to y+10 on the other triangle.

So we can write the equation x = y + 10.

Using this same method, the side that's equal to x + 2 is the same length as the side that's equal to 4y on the other triangle.

So, we can write the equation 4y = x + 2.

Now we have the equations \left \{ {{x=y+10} \atop {4y=x+2}} \right. you could rewrite to be in slope- intercept form so they're easier to graph. But a graphing calculator online would plot it just fine.

If you graph these two equations they'll intersect at the solution ( 14, 4 ). I'll include the graph in my images as well.

To check your answer, you can plug in x and y and see if the triangle sides end up being the same length. I did and it was correct.

a company donates 935 pencils to a school. the pencils are divided evenly among 9 classrooms. the rest of the pencils are given
wariber [46]
The problem deals with a division and the rest of it, that is dividing the total amount of pencils into 9 classrooms and the rest, lets express it as fraction:
935/9 = 103 + 8/9
that is, if we multiply 103*9 we get 927 and are 8 pencils left over, therefore, 8 pencils are donated to the library and each classroom gets 103 pencils, in total 935 pencils are donated.

What is the value of x in this diagram?
mixas84 [53]

Answer:

The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try!
