The lengths of two sides of a right angled triangle are 20 cm and 30 cm.
Calculate the length of the third side, if it is:
(a) the hypotenuse
(b) not the hypotenuse
Answers
Answers:
Part (a) 10*sqrt(13) Part (b) 10*sqrt(5)Those values are exact. They approximate to:
10*sqrt(13) = 36.0555
10*sqrt(5) = 22.3607
====================================================
Explanation:
Part (a)
If the unknown third side is the hypotenuse then we need to find the value of c when a = 20 and b = 30.
Apply the pythagorean theorem
a^2 + b^2 = c^2
20^2 + 30^2 = c^2
400 + 900 = c^2
1300 = c^2
c^2 = 1300
c = sqrt(1300)
c = sqrt(100*13)
c = sqrt(100)*sqrt(13)
c = 10*sqrt(13) .... exact length
c = 36.0555 ...... approximate length
------------------------------------
Part (b)
If the third side is not the hypotenuse then that must mean c = 30 is the hypotenuse as this side is larger than the 20 cm side. The hypotenuse is always the longest side.
Let a = 20 be the known leg. Let's find the other unknown leg b using the pythagorean theorem.
a^2 + b^2 = c^2
20^2 + b^2 = 30^2
400 + b^2 = 900
b^2 = 900-400
b^2 = 500
b = sqrt(500)
b = sqrt(100*5)
b = sqrt(100)*sqrt(5)
b = 10*sqrt(5) ..... exact length
b = 22.3607 ....... approximate length

What is multiplication?Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression for some number of times.
Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.
Given:
It takes the Sun about 2.3x10⁸ years to orbit the center of the Milky Way.
It takes Pluto about 2.5 times 10 squared years to orbit the Sun.
Pluto orbits the Sun while the Sun completes one orbit around the Milky Way,
= 2.3 x 10⁸ x (2.5 x 10)²
= 14.375 x 10¹⁰
Therefore, the required time is 14.375 x 10¹⁰ years.

Find the value of x:

Answer:
x = 3
Step-by-step explanation:
These angles are vertical angles. Vertical angles equals to on another but on the opposite side. Since they equal to another you do:
(10x + 1) = (12x - 5)
Add 5 on both sides:
10x + 6 = 12x
Subtract 10x on both sides:
6 = 2x
Divide 2 on both sides:
3 = x
Answer:
(10x+1)°=(12x-5)°. [vertically opposite angle]
1+5=12x-10x
6= 2x
3=x
therefore,x=3
Write a function rule for "The output is two more than one-fourth of the input ."
Answers
Answer:
y=(x/4)+2
Step-by-step explanation:
let y be the output and x be the input. So,
y=(x/4)+2
The function rule for " The output is two more than one-fourth of the input " is y = 2 + (1/4)x.
What is function?A function is a relation between a dependent and independent variable. We can write the example of functions as -
y = f(x) = ax + b
y = f(x, y, z) = ax + by + cz
Given is to find the function rule for "The output is two more than one-fourth of the input."
The given mathematical statement is - "The output is two more than one-fourth of the input."
Assume the input to be {x} and the output be {y}. So, we can write that -
(output) = (two) + (1/4)(input)
y = 2 + (1/4)x
Therefore, the function rule for " The output is two more than one-fourth of the input " is y = 2 + (1/4)x.

Answer:
A = (1/2)Pa = Pa/2
You can multiply both sides by 2 to eliminate the fraction on the right side:
2A = 2(Pa/2) = Pa
Then divide both sides by a (or multiply both sides by 1/a) to leave P alone on the right side:
(2A)(1/a) = 2A/a = (Pa)(1/a) = P
Rewriting:
P = 2A/a
You could also have divided by a first then multiplied by 2; which you should do first does not matter in this example.
