Answer:
3√2
Step-by-step explanation:
The congruent length of the triangle are the lengths with equal lengths. For an isosceles triangle, two of its sides are equal. In order to know the length of one of the congruent legs of JLK, we will find the distance between the adjacent point of the triangle.
Given triangle J L K has points J(2, 4), K(5, 1) andL (2, -2).
Using the formula to calculating distance between two points
D = √(x2-x1)²+(y2-y1)²
For side JK,
J(2, 4), K(5, 1)
JK = √(5-2)²+(1-4)²
JK = √3²+-3²
JK = √18
JK = 3√2
For side KL,
K(5,1), L(2, -2)
KL = √(2-5)²+(-2-1)²
KL = √-3²+-3²
KL = √18
KL = 3√2
For side JL
J(2, 4), L(2, -2)
JL= √(2-2)²+(-2-4)²
JL = √0²+-6²
JL = √36
JL = 6
SINCE JK = KL = 3√2, the length of one of the congruent legs is 3√2
Answer:
Step-by-step explanation:
Let the numbers of steps you can take to reach your goal be x
Your goal is to take at least 10,800 steps per day and you have walked 7370 steps already.
x + 7370 >= 10800
x >= 10800 - 7370
x >= 3430
Formula: cp1/cp2 = price1/price2
so let x be the new price,
38.8/130.7 = .25/x
x = .25*130.7/38.8
so, you get
x = 0.84
Answer:
The area of the pyramid is 360 unit²
Step-by-step explanation:
Given
Base Edge, a = 10
Height, h = 12
Required
Determine the surface area
The surface area of a regular pyramid is calculated as thus;
Substitute values for a and h
Evaluate all squares
Take positive square root of 169
<em>Hence, the area of the pyramid is 360 unit²</em>
