Let m = 10 and n = 2
We know:
y^2 = (m+n).m
y^2 = (10+2).10
y^2 = 120
y = √(120)
Then,
m^2 + x^2 = y^2
10^2 + x^2 = ( √( 120) )^2
100 + x^2 = 120
x^2 = 120 - 100
x^2 = 20
x = √(20)
x = √(4×5)
x = √(4) × √(5)
x = 2√(5)
I hope this has helped!
1) b + 14
sum= addition
2) y - 5
3) c + 7
more than= addition
4) 3 * b or 3b
product= multiplication
5) n/4 or n ÷ 4
In each of these expressions the letters represent an unknown number value. For example, in number 5), if n= 16, then we would divide 16 ÷ 4 which would equal 4.
Hope this helps! :)
40,810 if you mean 4 thousand 8 hundred and 10 then its 4,810
Answer:
125.141
Step-by-step explanation:
Assuming that this is an equilateral triangle, I am going to divide this triangle in half to get a right triangle.
17 is our hypotenuse
17/2 = 8.5, this is one of our legs
The other leg is our height, which we will find.
We use Pythagoras Theorem to find the height/leg:
= 14.72243186
Now, we use another formula to find the area of the triangle:
14.72243186 × 17 = 250.2813416
250.2813416 ÷ 2 = <u>125.1406708</u>
