If longest out of a triangle is 3 inches longer than the shorter side. The medium size is 2 inches longer than the shorter side. If the perimeter is 26 inches, what are the length of the three sides
Answers
Answer:
Shortest side = 7 inches.
Medium side = 9 inches.
Longest side = 10 inches.
Step-by-step explanation:
Let the shortest side be x.
Translating the word problem into an algebraic equation, we have;
Shortest side = x
Medium side = x + 2
Longest side = x + 3
The perimeter of a triangle is given by the addition of all its three (3) sides.
Mathematically, the perimeter of a triangle is given by the formula;
[tex] P = A + B + C [/tex]
Substituting into the equation, we have;
26 = x + x + 2 + x + 3
26 = 3x + 5
3x = 26 - 5
3x = 21
x = 21/3
x = 7 inches.
Therefore, the length of the three sides are;
Shortest side = x = 7 inches.
Medium side = x + 2 = 7 + 2 = 9 inches.
Longest side = x + 3 = 7 + 3 = 10 inches.
If 30% of a number is 15, what is 25% of the number?
Answers
Answer:
12.5
Step-by-step explanation:
Basically, the number was multiplied by .3 to get 15. So if you do 15/.3 you'll get your original number which is 50. Then you multiply by .25 and get 12.5.
A computer monitor is 23 inches which is the diagonal distance across the screen.If the screen measures 13 inches in height,what is the actual width of the screen to the nearest inch?
Answers
Answer:
width = 19 inches
Step-by-step explanation:
Pythagorean theorem
23^2 = 13^2+x^2
529 = 169+x^2
x^2 = 360
x = 18.97
The actual width of the screen to the nearest inches will be 18.97 inches.
What is a Pythagoras theorem?The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
The Pythagoras theorem formula is given as
H² = P² + B²
A PC screen is 23 inches which is the slanting distance across the screen.
If the screen measures 13 inches in height. Then the actual width of the screen will be given as,
23² = 13² + B²
529 = 169 + B²
B² = 360
B = √360
B = 18.97 inches
The actual width of the screen to the nearest inches will be 18.97 inches.

A 45-45-90 triangle has a leg of length 5.38. What is the length of the other leg?
Answers
Answer:
5.38 units
Step-by-step explanation:
Because of the base angle theorem converse, This triangle is an isosceles triangle.
Because this is an isosceles triangle, because the leg of the triangle is 5.38 units, that means the other leg has to be 5.38 units
You may be asking, how do I know it's the other leg that's congruent.
Well, the angle opposite to the 90° angle is the hypotenuse, and we want the line segment opposite of the 45° angle. And both the legs are opposite to the 45° angles.
Let me know if you have any questions.

a) 52.9ft
b) 17ft
c) 5.9ft
d)1.7ft
Answers
Answer:
b
Step-by-step explanation:
The maximum length of the beluga whale is 17 feet.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, The basking shark can grow to a length of 30 feet.
This is 176.47% of the maximum length of the beluga whale.
Assuming the maximum length of a beluga whale is x feet.
So, 176.47% of x is 30 feet.
∴ (176.47/100)×x = 30.
1.7647x = 30.
x = (30/1.7647).
x = 17 feet.
