A triangle with sides 11m , 13m and 18m is a right triangle. A True B False

Julli [10]

$\bold{\huge{\pink{\underline{ Solution}}}}$

$\bold{\underline{ Given :-}}$

A triangle with sides 11m, 13m and 18m

$\bold{\underline{ To \: Find :-}}$

We have to check it whether it is right angled triangle or not?

$\bold{\underline{ Let's \: Begin :-}}$

$\sf{\red{ In \:right \:angled\ : triangle, }}$

According to the Pythagoras theorem, The sum of the squares of perpendicular height and the square of the base of the triangle is equal to the square of hypotenuse that is sum of the squares of two small sides equal to the square of longest side of the triangle.

We imply it in the given triangle ,

$\sf{\red{ ( Perpendicular)² + (Base)² = (Hypotenuse)²}}$

$\sf{(AB)² + (BC)² = (AC)²}$

$\sf{ (11)² + (13)² = (18)² }$

$\sf{ 121 + 169 ≠ 324 }$

$\sf{ 290 ≠ 324 }$

From Above we can conclude that,

The sum of the squares of two small sides that is perpendicular height and base is not equal to the square of longest side that is Hypotenuse

$\sf{\blue{ Hence,\: Your\: answer \:is \:false }}$

What is the reciprocal of 6/5? a. 12/10 b. 1 1/5 c. 1 d. 5/6

galina1969 [7]

The reciprocal of a fraction is simply the reverse position of the original fraction, its numerator and denominator. It is represented by the formula of 1/number (fraction). To get the reciprocal of the number, divide one by the fractional number. You are given the number 6/5. So you have a numerator of 6 and a denominator of five. Simply swap them and you get the new numerator as 5 and the new denominator as 6. Or you can just divide 1/(6/5) then you will get 5/6. The answer is letter D.
