The length of the legs of this isosceles triangle is 19 meters.
A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
We know an isosceles triangle has two equal sides and their opposite angles are also equal.
Given, The leg of the isosceles triangle is two less than three times the length of its base.
Assuming the base to be x meter,
∴ The other two legs are (3x - 2).
The perimeter of the triangle is 45 m and we know it is the sum of the lengths of all the sides.
So, (3x - 2) + (3x - 2) + x = 45.
7x - 4 = 45.
7x = 49.
x = 7.
So, the length of the legs are (3.7 - 2) = 19 meters.

Answer:
19 m
Step-by-step explanation:
base=x
leg=3x-2
3x-2+3x-2+x=45
7x-4=45
7x=49
x=7
leg=3x+2=3(7)-2=19
notation?
Answer:
From the information given, the original price per pound was increased by $ 0.75
Let the original price be x, so the new price is x + 0.75
Sam bought 3 pounds of apples at new price and it cost him 5.88
so we form an equation:
3 (x + 0.75) = 5.88
3x + 2.25 = 5.88
3x = 5.88 - 2.25
3x = 3.63
x = 3.63 / 3
x = 1.21
Therefore the original price per pound is 1.21 dollars
Answer:
1.21=x
Step-by-step explanation:
Do
3 (x + 0.75) = 5.88
then 3x + 2.25 = 5.88
then 3x = 5.88 - 2.25
to 3x = 3.63
and last of allx = 3.63 / 3
