Answer :-
- Perimeter of the triangle is 55 units.
Given :-
- Two equal sides of an iscosceles triangle are 4x-2 and 3x+4. if the third side is 2x-1,find x. Hence,find the perimeter of the triangle.
To Find :-
- Perimeter of the triangle.
Solution :-
Here
Sides of the triangle are
- 4x - 2 units
- 3x + 4 units
- 2x - 1 units
As we know that
isosceles triangle have two sides equal.
So
⇒ 4x - 2 = 3x + 4
⇒ 4x - 3x = 4 + 2
⇒ x = 4 + 2
⇒ x = 6
Put the value of x in the sides
- 4x - 2 = 4(6) - 2 = 22
- 3x + 4 = 3(6) + 4 = 22
- 2x - 1 = 2(6) - 1 = 11
Perimeter of the triangle is
sum of all sides
⇒ 22 + 22 + 11
⇒ 55 units
Hence, the perimeter of the triangle is 55 units.
Answer: PLEASE BRAINLIEST MY ANSWER
∴ x = 6
∴ Perimeter of the triangle = 55
Step-by-step explanation:
Q) Two equal sides of an isosceles triangle are 4x-2 and 3x+4. if the third side is 2x-1,find x. Hence, find the perimeter of the triangle
⇒ From the given condition -
Let two equal sides of an isosceles triangle be a=4x-2 and b=3x+4 and remaining third side be c=2x-1.
∴ a = c
∴ 4x-2 = 3x+4
∴ 4x-3x = 4+2
∴ x = 6
now the given three sides are a, b, c -
1) a = 4x-2 = 4×6 - 2 = 24-2 = 22
2) b = 3x+4 = 3×6 + 4 = 18+4 = 22
3) c = 2x-1 = 2×6 - 1 = 12-1 = 11
∵ the three sides are 22, 22, 11.
Now,
Perimeter of the triangle = a + b + c = 22 + 22 + 11 = 55
Perimeter of the triangle = 55
