From the Special Triangle Theorem, the hypotenuse is equal to the side lengtht times the Sqrt(2).
So hypotenuse H = xSqrt(2), x=H/Sqrt(2).
Using numbers, if H = 7, then x = 7/Sqrt(2) = 7Sqrt(2)/2 to rationalize it.
Step-by-step explanation:
x + y = 9. => 2x + 2y = 18.
2x + 2y = 18
- (2x - 3y = -12)
=> 5y = 30, y = 6.
Therefore x + (6) = 9, x = 3.
The solution is x = 3 and y = 6.
Answer: the answer to this is 5n
Hi there!
Area of a triangle: 1/2bh
Substitute 6 for h and 12 for b.
1/2(12)(6)
Multiply (12)(6).
1/2(72)
Divide 72 by 2.
36
C) 36 sq. units
Hope this helps!
