Answer:
[tex]\sqrt{119}[/tex]
Step-by-step explanation:
Basically you need to have the third value of the other triangle to be able to solve for the other triangle. Use pythagorean theorem to find the missing values.
a^2+5^2=10^2
a^2+25=100
a^2=75
square root of 75
a=5[tex]\sqrt{3}[/tex]
5[tex]\sqrt{3}[/tex]^2+x^2=12^2
[tex]\sqrt{119}[/tex]
Answer:
8 1/3, or 8.307
Step-by-step explanation:
First we need to get the measurement of the division line, or the middle line. We can use the Pythagorean Theorem! How exciting!
[tex]10^{2} - 5^{2} = 75[/tex]
Now, you have two options:
A) If you are good at math and can understand shortcuts, there is no need to take the square root of this, as you will instantly have to square it as we use it in the second half.
B) If you need to have something written down for your though process, go ahead and square root 75.
I am going to use option A, but if you need me to explain why we do not have to take the square root, follow along, and if you still do not get it, do not be afraid to ask!
For the second half of the problem, to find x, we must again use the Pythagorean Theorem!
[tex]12^{2} = x^{2} + 75[/tex]
144 - 75 = 69
[tex]\sqrt{69} = 8.30662386292[/tex]
And now we are done, with a final answer of 8.307, or [tex]8\frac{1}{3}[/tex]!
Hope this helps! Math is fun!

The general form of the quadratic functions is represented as below:-
y = ax² + bx + c
Where a,b, and c are the constants x and y are variables.
The graph of the quadratic functions will be parabolic on the x-y plane.

Math problem: Pirate Captain William Hawk left his hat on Treasure Island. He sailed 18km northeast through the Forbidden Straight, the 11km southeast to his home before realizing it was missing. If he sent his parrot to fetch his hat, how far did it need to fly?
Answers
Answer:
7 km
Step-by-step explanation:
If I subtracted 18km by 11km my answer would be 7km
Answer:
21.1 km
Step-by-step explanation:
The northeast line and the southeast line will make a right angle so use the Pythagorean Theorem: a^2 + b^2 = c^2 and calculate c.
18² + 11² = c²
324 + 121 = c²
445 = c²
c = 21.1 km
1 foot = 12 inches. 1 inch = 2.5 centimetres. Change 5 feet 10 inches to centimetres
Answers
I guess the answer should be 177.8 cm.
The measurement of 5 feet 10 inches to centimeters is 175 centimeters.
What is Unit of Measurement?Units of measurement are defines ad the definite magnitude of a physical quantity. It is used to find a number that shows the amount of something.
Here we have to convert the units of measurement feet and inches to centimeters.
We have,
1 foot = 12 inches and 1 inch = 2.5 centimeters
We have to change 5 feet 10 inches to centimeters.
1 foot = 12 inches
⇒ 5 feet = 12 × 5 inches
= 60 inches
So, 5 feet 10 inches = 60 inches + 10 inches
= 70 inches
1 inch = 2.5 centimeters
70 inches = 70 × 2.5 centimeters
= 175 centimeters
Hence we got 5 feet 10 inches as 175 centimeters.

(2) (m - 8)(m + 8) (4) (m +16)(m - 4)
Explain why
Answers
Answer:
the correct option is number (3). It corresponds with the expression David factorised.
Step-by-step explanation:
David correctly factored the expression m² - 12m + 64, we want to check which one of the options he wrote.
(1) (m - 8)(m - 8) = (m - 8)²
= m² - 16m + 64
NOT THIS
(2) (m - 8)(m + 8) = m² - 8²
= m² - 64
NOT THIS
(3) (m - 16)(m + 4) = m² + 4m - 16m - 64
= m² - 12m - 64
THIS IS THE CORRECT OPTION AS IT CORRESPONDS WITH THE EXPRESSION DAVID FACTORISED
(4) (m + 16)(m - 4) = m² - 4m + 16m - 64
= m² + 12m - 64
NOT THIS
