Question

If two sides of a triangle are 6 cm and 10 cm, then the length of the third side can be what ?​

Answer 1

Answer:

let the 3rd side be x

and the sum of 3 side be (6+10+x)cm

= x+6+10=6+10+x

= x+16=16+x

=x= 16+16+x

x=32+x

2x=32

x=32/2

x=16

the third side be 16

Answer 2

Answer:

It depends. Let us take the measurements as the base and height.

Step-by-step explanation:

Base=6 cm

Height=10 cm

The third side is called the hypotenuse.

To find it, we use Pythagorean Theorem.

a^2 + b^2 = c^2

(Note: "^" is power or exponential value.)

a=height

b=base

c=hypotenuse

So we input our values:

a^2 + b^2 = c^2

10^2 + 6^2 = c^2

100 + 36 = c^2

136 = c^2

To remove the power, we apply square roots.

√136 = √c^2

Square root cancels out power of 2.

√136 = c

11.6619037897 = c

11.66 ≈ c

Let me know if it works.
