Answer:
a = 33cm
b = 33cm
c = 11cm
Step-by-step explanation:
Let us say that the sides of the triangle are <em>a, b and c</em>
The perimeter of a triangle can be calculated by adding all three sides of the triangle.
Perimeter = <em>a + b + c</em>
<em />
Let side <em>c</em> be the shortest side of the triangle.
From the statement "Each of the two longer sides of the triangle is three times as long as the shortest side" we can have that
<em>a = 3c and b = 3c</em>
We can input these values into the perimeter of the triangle
Perimeter = <em>3c + 3c + c = 77</em>
<em>Perimeter = 7c = 77</em>
<em>c = 11</em>
The shortest side, c is = 11 cm
side a is 3 X 11 = 33cm
side b = 3 X 11 = 33 cm
Divide the top number by the bottom number
Answer:
(a) Lying on both axes-
Point lying on both axes will lie on origin, so its coordinate is (0,0)
(b) Lying on x-axis and with x-coordinates 4
Since the point lies on x-axis so its y-coordinate is 0, so its coordinate is (4,0)
(c) Lying on y-axis and y-coordinates -3
Since the point lies on y-axis so its x-coordinate is 0, so its coordinate is (0,-3)
Answer:12 m
Step-by-step explanation:
Given
Width of garden 
Total fencing 
If Lulu has enough fencing to go around her rectangular garden then , it should be equal to perimeter of garden
Suppose L is the length of garden
Therefore perimeter is 
thus length of fencing is 
Answer:
k= 8/5
Step-by-step explanation:
here x= 5 and y= 8
we have y=kx
k= y/x
k= 8/5 this is constant of variation
