Question

Assertion (A) The length of three sides of triangle are 26 cm, 28 cm and 30 cm. The height corresponding to base 28 cm is 24.

Reason (R) If the base of an isosceles triangle be 6 cm and each of the equal sides be 5 cm, then its height is 6 cm.​

Answer 1

Answer:

Assertion is Wrong And Reason Is Correct

Step-by-step explanation:

In A Isosceles Triangle Two Sides Are

Answer 2

The length of three sides of triangle are in $42cm,$ The base of an isosceles triangle the $4cm.$

Step-by-step explanation:

$a=26cm$,$b=28$ and $c=30cm$

$=42cm$

$=\sqrt{42(42-26)(42-28)(42-30)}$

$=\sqrt{42*12*16*14} }$

$=\sqrt{14*3*2*3*2*4*4*14}$

$=14*4*2*3$

$=336cm^{2}$

The height of the triangle corresponding to $28cm$ is given by

Area of triangle=$336cm^{2}$

height=$=\frac{336*2}{28}$

$=24cm$.

$=\frac{1}{2}\sqrt{4(5)^{2}-6^{2}}$

$a=5cm, b=6cm$

$=\frac{1}{2} *\sqrt{100-36}$

$=\frac{1}{2}*8$

$=4cm$.
