What else would need to be congruent to show that JKL= MNO by AAS?
taurus [48]
Answer: Choice B) Angle L = Angle O

---------------------------------------------------
---------------------------------------------------

If we know that Angle L is congruent to Angle O, then we can use the AAS (angle angle side) congruence property. We have one pair of angles marked by the square marker (angle J and angle M). So they are congruent angles. We have a pair of congruent sides JK = MN = 3. So we're just missing a pair of angles. 

Note: The answer is NOT angle K = angle N because this would mean ASA would be used instead of AAS. The order of the letters is important as it establishes how the sides and angles relate. With ASA, the side is between the angles. With AAS, the side is not between the angles.

Here is a right cone:
11111nata11111 [884]

Answer:

Choice B: A triangle

Choice C : A shape with two edges, one straight and one curved

Step-by-step explanation:

When a cone is cut by a plane that runs exactly through its vertex, and perpendicular to its base, the shape that is obtained is an isosceles triangle, when the section is viewed.

When a cone is cut through a plane that runs perpendicularly to its base, but not through its vertex, we can get two different shapes which have parabolas or hyperbolas as their curved edge, and a straight edge which is formed from the base of the cone

Scarlett is working two summer jobs, making $13 per hour landscaping and making $8 per hour clearing tables. In a given week, sh
dolphi86 [110]

Answer:

The graph in the attached figure

Step-by-step explanation:

Let

x ----> the number of hours landscaping

y ---->   the number of hours clearing tables

we know that

she can work a maximum of 12 total

so

x+y\leq 12 ----> inequality A

she must earn a minimum of $120

so

13x+8y\geq 120 ----> inequality B

Solve the system of inequalities by graphing

The solution is the triangular shaded area

see the attached figure

Remember that

If a ordered pair is a solution of the system of inequalities, then the ordered pair must satisfy both inequalities (the ordered pair lie in the shaded area of the solution set)

One possible solution is the point (10,1)

The point (10,1) lie in the shaded area

That means

The number of hours landscaping is 10 and the number of hours clearing tables is 1
