XXe: A+C=B+D z tego wyliczysz kąty

Kasia: dalej mi to nie ułatwia sprawy... function(searchElement){"use strict";if(this===void 0||this===null)throw new TypeError();var t=Object(this);var len=t.length>>>0;if(len===0)return-1;var n=0;if(arguments.length>0){n=Number(arguments[1]);if(n!==n)n=0;else if(n!==0&&n!==(1/0)&&n!==-(1/0))n=(n>0||-1)*Math.floor(Math.abs(n))}if(n>=len)return-1;var k=n>=0?n:Math.max(len-Math.abs(n),0);for(;k<len;k++){if(k in t&&t[k]===searchElement)return k}return-1}

XXe: no jak to nie 872

Kasia: to rozwiąż bo jakoś mi to się nie udaje function(searchElement){"use strict";if(this===void 0||this===null)throw new TypeError();var t=Object(this);var len=t.length>>>0;if(len===0)return-1;var n=0;if(arguments.length>0){n=Number(arguments[1]);if(n!==n)n=0;else if(n!==0&&n!==(1/0)&&n!==-(1/0))n=(n>0||-1)*Math.floor(Math.abs(n))}if(n>=len)return-1;var k=n>=0?n:Math.max(len-Math.abs(n),0);for(;k<len;k++){if(k in t&&t[k]===searchElement)return k}return-1}

Kasia: naprawdę nikt nie potrafi mi pomóc?.. ehh.. proszę raz jeszcze bardzo o pomoc.. function(searchElement){"use strict";if(this===void 0||this===null)throw new TypeError();var t=Object(this);var len=t.length>>>0;if(len===0)return-1;var n=0;if(arguments.length>0){n=Number(arguments[1]);if(n!==n)n=0;else if(n!==0&&n!==(1/0)&&n!==-(1/0))n=(n>0||-1)*Math.floor(Math.abs(n))}if(n>=len)return-1;var k=n>=0?n:Math.max(len-Math.abs(n),0);for(;k<len;k++){if(k in t&&t[k]===searchElement)return k}return-1}

XXe: ok juz zrobie

XXe: to z kątami a) a+c=3x b=2x a+c=b+d 3=2+d d=1 a+c=180 3x=180 x=60 stopni

XXe: c) a:b:c=1:2:3 a=x b=2x c=3x d=2x(45°)
