Step-by-step explanation:
we know that perimeter of triangle is equals to side + side + side
but we can see that the particular triangle is having all the sides equal so it is seen to be equal lateral triangle and formula of equilateral triangle is 3 × sides.....
So,We will take sides common.....
Perimeter of equilateral triangle= 3×Side
3×4.6 cmsq.
13.8cmsq. Answer
X= 50
Replace the x with the given number.
Y= 50-20
Y= 30
Here we will use the trial and error method.
- We will try putting different values of x.
<h3 /><h3>1st of all</h3><h3>x=1</h3>





<h2>Now,</h2><h3>x=2</h3>




<h2>Again,</h2><h3>x=3</h3>




<h3>☣Hence, The value of X as 3 satisfies the equation!</h3>
