Step-by-step explanation:
In 30-60-90 triangles, if the hypotenuse is <em>x</em>, the longest leg is , and the shortest leg is
.
If the longest leg is 6, then
Multiply by 2,
If x=12,
So, the shortest leg is 6√3.
Answer:
f+g is right answer.
Step-by-step explanation:
given
,
2x+3 is given and we have to find the combinations of h,f and g.
By trial and error we check h+f
= -4x-2
h-f = 10x-6
So these two are not correct
Try with h+g = 12x-3 and h-g = -6x-5
Hence these are also not right
Try with f+g
(f+g)(x) = f(x)+g(x) = -7x+2+9x+1 =2x+3
Hence f+g is right.
