Anmol got 60 marks out of 80 marks in mathematics what percent marks did he get

75%

Step-by-Step Explanation:

There are two ways to go about this.

1) We can simply put it as a fraction = 60/80.

  Then since a fraction sign also means division, we divide 60 by 80 = 0.75

  Then to change a decimal into a percentage, we multiply by 100% = 75%

  So our answer is 75%

2) We can simply it after it is put into a fraction = 60/80 = 3/4

   It should be common knowledge that 3/4 is 75% depending on what                 grade you are in.

But there you have it, whichever way you prefer, the answer is always 75%.

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
