In this problem, the shape of the sail is equilateral triangle. You are given that the measurement of each side is x – 10 units. The perimeter is 63 units. You have to formulate an equation to find the value of x. The formula of the perimeter is to get the sum of the measurements of the three sides of the triangle.

x – 10 + x – 10 + x – 10 = 63

3x – 30 = 63

3x = 63 + 30

3x = 93

x = 31

Therefore, the value of x is 31 and the measurement of each sides is 21 units.

A triangle has sides with lengths of 26 meters, 39 meters, and 43 meters. Is it a right triangle?
Ivanshal [37]

Answer: No

Step-by-step explanation:

This triangle is not a right triangle because:

A right triangle must have one side that is exactly 90°.

A triangle with sides 26, 39, and 43 do not have any sides that total 90.

The answer to your question is no.

Best of Luck!

The sum of three consecutive integers is 90. Find the three numbers by letting x
Law Incorporation [45]

Answer:

x = 28

Step-by-step explanation:

let us take three consecutive numbers be (x + 1), (x + 2) and (x + 3)

Now,

The sum of three consecutive integers is 90

i.e.,

(x + 1) + (x + 2) + (x + 3) = 90

x + 1 + x + 2 x + 3 = 90

3x + 6 = 90

3x = 90 - 6

3x = 84

x = 84/3

x = 28

x = 28Thus, The value of x is 28

<h2><em><u>VERIFICATION</u></em><em><u>:</u></em></h2>

(x + 1) + (x + 2) + (x + 3) = 90

(28 + 1) + (28 + 2) + (28 + 3) = 90

28 + 1 + 28 + 2 + 28 + 3 = 90

90 = 90
