I am very confused (I didn’t mean to press B)

The anwer is A

Step-by-step explanation:

If it is a right angle triangle we use paythagoras theorem

a ×a + b× b= c × c

1. 15× 15( square of 15) + b× b(square of b) = 17 ×17 (square of 17)

;2. 225 + b×b(square of b ) = 289

3. b×b(square of b) = 289-225

4. b × b( square of b )= 64

b = 8

I hope it is helpful

c.35

step-by-step explanation:

8+13=21

21+8=29

29+6=35

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
