Answer for number 7 is A.
Answer:
So
will be equivalent to
in radical form
Step-by-step explanation:
We have given expression 
We have to write this in radical form
We know that if any fraction is in exponential form then if we write this in radical form then in radical form the exponent come inverse of its number
So
can be written in radical form as 
So
will be equivalent to
in radical form
Answer:
The two angles are 85 and 95 degrees
Step-by-step explanation:
Supplementary angles add to 180
Let x be one angle
The supplement is 10 less, ( x-10)
They add to 180
x+ ( x-10) = 180
2x -10 = 180
Add 10 to each side
2x-10+10 =180-10
2x= 190
Divide by 2
2x/2 =190/2
x=95
The other angle is 95-10 = 85
The two angles are 85 and 95 degrees
-3 is in the opposite direction of V
