Answer: The answer is "there is a difference of 30°".
Step-by-step explanation: We are given to compare an angle having a measure of 120° with that of an angle having a measure of 
radians.
Let the two angles be represented as follows:
We have the following relation between degree and radian:
Therefore,
Hence,
Thus, the difference is 30°.
If we draw a rhombus OABC on a coordinate grid with one vertex at the point O (0,0)
and let its height be 1 then (using the Pythagoras theorem) the coordinates of the 4 points will be as follows:-
O = (0,0) , A = (1, 1), B = (sqrt2+ 1 , 1) , C = (sqrt2, 0)
Slope of the diagonal OB = 1 / (sqrt2 + 1)
Slope of the other diagonal AC = - 1 / (sqrt2 - 1)
Product of the slopes = - 1 / ( sqrt2 + 1)(sqrt2 - 1) = -1 / 1 = -1
This proves that the diagonals are perpendicular.
Here is your answer
D) x= -1 or x= 7
REASON:
Given equation-
Split the middle term
Taking common from the terms
Now,
x+1=0 or x-7=0
x= -1 or x= 7
