Jocelyn Said That The Triangle Below Is Not A Right Triangle. Her Work Is Shown Below. Explain What She

Answers

Answer 1

Complete Question:

Jocelyn said that the triangle below is not a right triangle. Her work is shown below. Explain what she did wrong, and show Jocelyn the correct solution.

We need to check if 27² + 45² = 36² is a true statement. The left side of the equation is equal to 2,754. The right side of the equation is equal to 1,296. That means 272 + 452 = 362 is not true, and the triangle shown is not a right triangle

Answer/Step-by-step explanation:

Jocelyn used a wrong equation and statement.

Here's what she should have stated and done.

Using the converse of Pythagorean Theorem, which says that a triangle with sides a, b, and c is a right triangle if it satisfy the statement: a² + b² = c².

Where, c is the hypotenuse which is the longest leg. While a and b are the side lengths of the other two legs.

Therefore, in this case,

c = 45

b = 27

a = 36

Thus, what we need to check to be true would be:

36² + 27² = 45² (this is where Jocelyn made a mistake. Jocelyn wrote 27² + 45² = 36² rather)

Let's check if it's true.

2,025 = 2,025 (this is true)

Therefore, the triangle is a right triangle.

O Justin should have added 3.8 and 7.9 first.

Answers

Answer:

C.) Justin should have multiplie 3.8 and 7.9 first.

Step-by-step explanation:

To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression.

City y is 10 miles north of city x city z is 24 miles east of city x how long is the straight roads connecting cities y and z?

Answers

Answer:

26 miles

Step-by-step explanation:

Using Pythagoras rule :

d = straight road connecting city Y and Z :

d = sqrt(xy² + xz²)

d = sqrt(10² + 24²)

d = sqrt(100 + 576)

d = sqrt(676)

d = 26 miles
