15, because angle L and N are equal, 3x=x+10 so x=5, plugging it in, we get that MN is 15

Answer:

Option A. MN=15\ units

Step-by-step explanation:

we know that

An isosceles triangle has two equal sides and two interior equal angles

The triangle LMN is an isosceles triangle

therefore

ML=MN

substitute the values

3x=x+10

solve for x

3x-x=10

2x=10

x=10/2=5\ units

Find the length of MN

MN=x+10 -----> MN=5+10=15\ units

SVETLANKA909090 [29]

Answer:

Scale is 1/6

Step-by-step explanation:

Since all sides and angles are identical these are congruent triangles

3 ways to solve:

Scale Factor = DE / AB = 12/72 = 1/6

Scale Factor = DF/AC = 7/42 = 1/6

Scale Factor = EF/CB = 11/66 = 1/6

In Exercises 10–14, use the diagram to determine whether you can assume the<br> statement.
lukranit [14]

Answer:

  it depends on what he means

Step-by-step explanation:

The friend needs to clarify the meaning of "if three lines intersect each other." If Line A intersects lines B and C, there will be two points of intersection, one at line B and one at line C.

If those lines are all in the same plane, and B and C are not parallel, so that line B intersects line C, then there will be a total of three points of intersection.

If the point of intersection of B and C is also the point where line A intersects them, then there will be only one point of intersection.

__

So, if the meaning is "if there are three non-parallel lines in the same plane, and each intersects the other two", then the Line Intersection Postulate guarantees there will be 1 or 3 points of intersection.

If the meaning is "if there are three lines not necessarily in the same plane, and one intersects the other two (but those two don't intersect each other)", then there may be 1 or 2 points of intersection (allowing that all lines may intersect at the same point).

Part A: A circle is the set of all points that are the same distance from one given point. Find an example that contradicts this
IRINA_888 [86]

Answer:

  • a sphere
  • the definition needs to restrict all of the points to a plane

Step-by-step explanation:

In 3-dimensional Euclidean space, a sphere is the set of all points the same distance from a given point. The given definition of a circle only applies when the given point and the solution set are in the same plane, and the geometry is Euclidean.

The volume of a cube is 460cm3.<br> Work out the length of its side rounded to 1 DP.
yaroslaw [1]
The side length is the cube root of 460.

cube root(460) = 460^(1/3)
That's approximately 7.7
