State if the triangles are similar. If so, how do you know they are similar and complete the similarity statement. Triangle LKJ≈
Llana [10]

Answer: C) similar, SAS similarity, triangle LQR

==============================================

Explanation:

The vertical angles KLJ and QLR are congruent. This forms the "A" in "SAS". The angles in question are between the marked sides.

KL = 18 is twice that of QL = 9, or put another way, KL/QL = 18/9 = 2. The ratio of the sides is 2. Also, JL/RL = 16/8 = 2 is the same ratio. Because both pairs of sides have the same ratio, the sides are in proportion. This helps form the two "S" letters of "SAS".

The original triangle has LKJ mentioned at the top. Note the order as its important. We start with L and move to K, so LK is the first segment mentioned. LK = 18 pairs up with LQ = 9, meaning that LQ must be the first segment mentioned of the answer triangle. Therefore LQR is the correct letter sequence if we start with point L. Writing QLR is not correct because Q is the first letter here but Q does not pair up with L.

Abigail has 16 apples she eats 2 apples per day.let y be the apples remaining as a function of the number of week,x
Greeley [361]

Answer:

Let X be the number of weeks.

2x - 16 = 14

   we add 16 on both sides.

2x = 30

now we divide 2 on both sides to get rid of the 2 to the x, we want to get x on its own.

X = 15

What is 4x-9(-3)=-48?
Ilia_Sergeevich [38]

Answer:

x = 5.25

Step-by-step explanation:

We are given the equation;

4x-9(-3)=-48

Opening the brackets

4x + 27 = 48

Combining the like terms together

4x = 48 -27

4x = 21

Solving for the value of x

x = 21 ÷ 4

  = 5.25

Thus, the value of x is 5.25
