Pythagoras' Theorem only works with right angle triangles.
A makes a right angles triangle because:
√3² + 4² = 5
However B doesn't because:
√7² + 8² = 10.631 (which is not 9)
Nor does C because:
√3² + 9² = √90 (which is not √95)
So the answer is A
Answer:
73
Step-by-step explanation:
(7.7 * 2) + (9.6 * 6) = 74
Answer:
a = 25
b= 1
![25(1 + \sqrt{2} )](https://tex.z-dn.net/?f=25%281%20%2B%20%20%5Csqrt%7B2%7D%20%29)
-Expand the brackets first
-than rationalise , to remove the square root from the denominator.
-lastly, simplify.
Hope I was able to help:)))
