Answer:
12 units
Step-by-step explanation:
Properties of Rhombus:
1. length of all sides are equal.
2. Diagonals bisect each other at right angles
As the length of all sides are equal,
JM = JK
3x = 2x + 4
Subtract 2x from both sides,
3x - 2x = 4
x = 4
JM = 3*4 = 12 units
Answer:
420
Step-by-step explanation:
The number of students in the school is unknown, so we'll call it x.
55% of the number of students are girls.
There are 321 girls.
55% of x = 231
0.55x = 231
x = 231/0.55
x = 420
Answer: 420
Answer:
The answer is 6b
Step-by-step explanation:
1) Regroup terms.
![3(a + 2b) - 3a](https://tex.z-dn.net/?f=3%28a%20%2B%202b%29%20-%203a)
2) Expand by distributing terms.
![3a + 6b - 3a](https://tex.z-dn.net/?f=3a%20%2B%206b%20%20-%203a)
3) Collect like terms .
![(3a + 3a) + 6b](https://tex.z-dn.net/?f=%283a%20%2B%203a%29%20%2B%206b)
4) Simplify.
![6b](https://tex.z-dn.net/?f=6b)

Answer:
FALSE: An angle of the triangle is bisected.
TRUE : A perpendicular segment is created from a vertex to the opposite side.
TRUE: A side of the triangle is bisected.
TRUE: The center of the triangle is found.
Step-by-step explanation:
Median: Median of a triangle is a line segment which joins the vertex of a triangle to the mid point of its opposite side.
1) A median is also a angle bisector of the vertex through which it passes but ONLY in ISOSCELES and EQUILATERAL TRIANGLE.
2)A perpendicular segment is created from a vertex to the opposite side. This is true for all the types of triangle.
3)A side of the triangle is bisected. Yes, the side of the triangle on which the median falls, is bisected.
Median divides the side of the triangle in to two equal sides.
4)The point where all the three median of the triangle intersect inside the triangle.That point is called the centro-id of the triangle.
Hence, the centroid of the triangle is found.
