Question

the length of the sides of a triangle are 11 cn,13cm,12cm find the length of median drawn to the largest side​

Answer 1

Step-by-step explanation:

GIVEN SIDES OF A TRIANGLE IS 11CM,12CM,13CM

WE KNOW THAT

LENGTH OF MEDIAN =

$( \sqrt{ {2b}^{2} \: + {2c}^{2} - \: {a}^{2} } )\div 2$

side lengths are a = 11 ,b= 13 ,c= 12

$\sqrt{2 \times {11}^{2} \: + 2 \times {1</em></strong><strong><em>2</em></strong><strong><em>}^{2} - \: {1</em></strong><strong><em>3</em></strong><strong><em>}^{2} } \div 2$

$\sqrt{2 \times121 \: + \: 2 \times </em></strong><strong><em>1</em></strong><strong><em>4</em></strong><strong><em>4</em></strong><strong><em> \: - </em></strong><strong><em>1</em></strong><strong><em>6</em></strong><strong><em>9</em></strong><strong><em>} </em></strong><strong><em>÷</em></strong><strong><em> 2$

√ 367

$</em></strong><strong><em>1</em></strong><strong><em>9</em></strong><strong><em>.</em></strong><strong><em>1</em></strong><strong><em>5</em></strong><strong><em>7</em></strong><strong><em>2</em></strong><strong><em>$

length of median drawn to longest side = 19.1572

we know according to pythagorous theorem that the square of the longest side is equal to the sum of squares of other two sides. and the other two sides are: 12cm and 5cm. ... yes the triangle given over here is right angled triangle as the square of the longest side is equal to the sum of squares of the other two sides.Feb 8, 2018
