two-fifths of a number is decreased by three.find the value of the expression if the number is twenty five

1 answer:

7 0

The expression would be written as:

$\frac{2}{5}$ n-3

N is any number. This expression means two-fifths of a number, subtract three. Now substitute 25 for n.

$\frac{2}{5}$ (25)-3
=10-3
=7

Answer:

u = 150

Step-by-step explanation:

Number of vertices:

Find the sum of the interior angles:

180(n - 2)

180(10 - 2)

180(8)

1440

To find u:

u = 1440 - (130 + 145 + 160 + 150 + 130 + 150 + 125 + 155 + 145)

u = 1440 - (1290)

u = 150

Which method would you use to prove that the two triangles are congruent?

Alona [7]

Answer:- AAS postulate

Explanation:-

AAS postulate tells that if two angles and a non-included side of a triangle to equal to the two angles and a non-included side of another triangle then the two triangles are said to be congruent.

Given:- One angle and one side of a triangle is equal to the one angle and one side of the other triangle.

We see there is one more pair of equal angles as they are vertically opposite angles . [See the attachment]

⇒ there is a triangle where two angles and a non-included side of a triangle to equal to the two angles and a non-included side of another triangle then the two triangles are said to be congruent.

⇒ The triangles are congruent [ by ASA postulate]
