Danielle is playing a game. she started with 10 points. in the first round she lost 20 points. in the second round she won 40 points what is her score

Given =

Danielle is playing a game

She started with 10 points In the first round she lost 20 points & second round she won 40 points.

find out Danielle  score

To proof

let us assume that the score of the danielle be x.

As given in the  question

She started with 10 points

in first round she lost 20 points

in second round she won  40 points

thus the equation becomes

x = 10 - 20 + 40

solving the above equation

we get

x = 30

thus the score of the Danielle is 30 points.

Hence proved

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
