Since lines a and c are parallel and we are given that c is perpendicular to b, we can infer that b is also perpendicular to a.
So, a and b are perpendicular, the angle formed by these lines should be 90.
Hence, angle 2 is 90.
Hope this helps :)

Complete question :
A 48 inch board in to be cut into three pieces so that the second piece is twice as long as the first, and the third piece in 3 times as long as the first. If x represents the length of the first, find the lengths of all three
Answer:
Length of first piece = x = 8
Length of second = 2x = 8*2 = 16
Length of third = 3x = 8 * 3 = 24
Step-by-step explanation:
Let :
Length of first piece = x
Length of second = 2x
Length of third = 3x
The total lengtb of board = 48 inches
Hence,
First + second + third = 48
x + 2x + 3x = 48
6x = 48
x = 48 / 6
x = 8
Length of first piece = x = 8
Length of second = 2x = 8*2 = 16
Length of third = 3x = 8 * 3 = 24
Answer:
The IQR of the given data is 6. Therefore the correct option is B.
Step-by-step explanation:
The formula for interquartile range is
In a box plot the left end of line represents the minimum value of data set and right end of line represents the maximum value of data set.
The left end of box represents the first quartile and right end of the box represents the third quartile. The line between the box represent the median.
From the given box plot it is clear that,
The interquartile range of the data is
The IQR of the given data is 6. Therefore the correct option is B.
We can solve this problem by using the distance formula. The distance formula is: 
We can now put in values and solve.
