The answer is -6 -/+ 4i. Hope this helps.
first, consider that 25 = 5^2, and -25 = -1*25 = -1*5^2.
Then, you can write:
![\sqrt[]{-25}=\sqrt[]{(-1)(25)}=\sqrt[]{(-1)(5^2)}=5\sqrt[]{-1}=5i](https://tex.z-dn.net/?f=%5Csqrt%5B%5D%7B-25%7D%3D%5Csqrt%5B%5D%7B%28-1%29%2825%29%7D%3D%5Csqrt%5B%5D%7B%28-1%29%285%5E2%29%7D%3D5%5Csqrt%5B%5D%7B-1%7D%3D5i)
because i = √-1.
Hence, the answer is 5i

Answer:
AS IT IS RIGHT ANGLE .
THEREFORE, 1 ANGLE =90°
A=55°,
LET LAST ANGLE BE Y.
THEREFORE, Y=90-55=35°
RATIO OF A:Y=55:35=11/7
RATIO OF ANÔTHER SIDE :X=11:7
HYPOTENOUES=8
THEREFORE8^2=11X^2+7X^2
64=121X^2+49X
