Answer:

We know that the exterior angle of a triangle is equal to the sum of two opposite interior angle. 

Step-by-step explanation:

25x + 57 + x = 45x

26x + 57 = 45x

57 = 45x - 26x

19x = 57

Therefore x = 3

A student gets 68 marks n therefore gets 85 percent total marks are?

mihalych1998 [28]

Answer:

There are 80 marks in total.

Step-by-step explanation:

Let the number of total marks be $x$ .

The percentage score of the student can be written as the ratio

$\displaystyle \frac{68}{x} = 85\%$ .

However,

$\displaystyle 85\% = \frac{85}{100}$ .

Equating the two:

$\displaystyle \frac{68}{x} = \frac{85}{100}$ .

Cross-multiply (that is: multiple both sides by $100x$ , the product of the two denominators) to get

$85x = 68\times 100$ .

$\displaystyle x = \frac{68\times 100}{85} = 80$ .

In other words, there are 80 marks in total.

Lets say your numbers are these...

10,20,30,40,50,60,70,80,90 and 100

you would add those to get 650

Now how many numbers did you add?

You added 10

so now divided

650 by 10

you get 65

that is the mean of those numbers!
