Prove: ∆LKM ≅ ∆JKM
Which method can you use to prove these triangles congruent?
the ASA Postulate
the SAS Postulate
the HL Theorem
the AAS Theorem
Answer: the ASA Postulate
Step-by-step explanation:
In the given picture , we have two triangles ∆LKM and ∆JKM , in which we have
[common]
By using ASA congruence postulate , we have
∆LKM and ∆JKM
ASA congruence postulate tells that if two angles and the included side of a triangle are congruent to two angles and the included side of other triangle then the triangles are congruent.
Answer:
ASA

Answer:
21 birds.
Step-by-step explanation:
Let B represent the number of birds and C represent the number of cats.
We have been given that an animal shelter spends $1.50 per day to care for each bird, so the amount spent on B birds will be 1.50B.
The animal shelter spends $8.50 per day to care for each cat, so the amount spent on C cats will be 8.50C.
Alexander noticed that the shelter spent $108.00 caring for birds and cats on Tuesday. We can represent this information in an equation as:
Alexander found a record showing that there were a total of 30 birds and cats on Tuesday. We can represent this information in an equation as:
We will use substitution method to solve system of linear equations.
From equation (2) we will get,
Substituting this value in equation (1) we will get,
Let us subtract 255 from both sides of our equation.
Let us divide both sides of our equation by -7.
Therefore, there were 21 birds at the shelter on Tuesday.
The shape of the mirror is Pentagon.
18. the length of each side of the church window is 20 inches, option A is correct.
Josie's mirror has 5 sides, which means it is a polygon with five edges.
The specific term used to describe a polygon with five sides is a pentagon.
A pentagon is a geometric shape with five sides and five angles. Each side of a regular pentagon is of equal length, and each interior angle measures 108 degrees.
In the case of Josie's mirror, since it has 5 sides, it is referred to as a pentagon.
18. Given that the church window has a perimeter of 80 inches and it is in the shape of a square.
We can find the length of each side by dividing the perimeter by 4 (since a square has four equal sides).
Perimeter = 4 × Length of each side
80 inches = 4 × Length of each side
Dividing both sides by 4:
Length of each side = 80 inches / 4
= 20 inches
Therefore, the length of each side of the church window is 20 inches.
