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:
x = 30
Step-by-step explanation:
The sum of the 3 interior angles of a triangle = 180°, hence
x + x + 10 + 3x + 20 = 180
5x + 30 = 180 ( subtract 30 from both sides )
5x = 150 ( divide both sides by 5 )
x = 30
Answer: I got 23/10, or 2.3
Step-by-step explanation:
Yo subtract 5- 2.75 and you get 2.25. 2.25 divided by .375 is 6 so 6 deli sandwiches were made
