One side of an isosceles triangle has a length of 19 m. The lengths of the other two sides are equal to one another, but are unknown. If the perimeter of the triangle is 51 m, what is the length of each unknown side?

Answers

Answer 1
Answer: Let x= side 1= 19
Let y= side 2=unknown
Let z= side 3=unknown
Since it is an isosceles triangle, two sides are equal, which happen to be y and z
Hence y=z

Perimeter of a triangle = Sum of all three sides
= x+y+z
51=19+2y [since we know x=19 and y=z, we know the perimeter is 51]
Solve now
32=2y
16=y
Since y=z
z= 16
Hence the unknown side's length is 16m
Answer 2
Answer: So the perimeter is 51. The base is 19. Subtract 19 from 51. 51 - 19 = 32. So 32 is the total length of the two equal unknown sides added together. Because the two sides must be equal, you can just divide 32 by 2. 32/2 = 16. Each of the two congruent sides are 16 m.

Given: B is the midpoint of AC
EB=BC

Prove: AB=BC

Answers

Answer:

Step-by-step explanation:Since B is the midpoint of AC, this means that AB and BC are equal in length, as the midpoint of a line segment divides it into two equal parts.

2. Let's assume that AB is not equal to BC. In this case, one of the line segments AB or BC would be longer than the other.

3. Since EB = BC, if AB is longer than BC, then EB would be shorter than AB. But since B is the midpoint of AC, EB and BC should be equal in length.

4. Similarly, if BC is longer than AB, then EB would be longer than BC. But again, EB and BC should be equal since B is the midpoint of AC.

5. Since assuming AB is not equal to BC leads to contradictions, our assumption is false. Therefore, AB must be equal to BC.

What is the product of 3/5 of 10

Answers

First, I would change the 10 to 1/10 and write it out as 3/5 = x/10. Then, I would multiply 10 x 3 to get 30. Next, I would figure out 30 divided by 5. Therefore, your answer would be 6 :)

The solution of the product of the two given numbers 3/5 and 10 is 6.

An arithmetic procedure known as multiplication combines two or more integers to get the sum of the products. Along with addition, subtraction, and division, it is a fundamental mathematical operation.

The numbers being multiplied are referred to as the factors in multiplication, while the outcome is referred to as the product. The multiplication operation is indicated by the symbol "" or "*," and it has certain characteristics and regulations.

The two numbers will be multiplied as below,

P = 3/5 x 10

P = 3 x 2

P = 6

Therefore, the product is 6.
