Question

need to find b in this situation

Answer 1

area = base*height

base = b, height = asin(u)

area = 11 = b*5sin(pi/4)

Answer 2

sin(pi/4) = sqrt(2)/2

Answer 3

11= 5sqrt(2)b/2

22/(5sqrt(2)) = b

Answer 4

didn't work :/

Answer 5

aww, value of a....

Answer 6

maybe 11sqrt(2)/5 (which is the same value)

Answer 7

didn't work either

Answer 8

5.5sqrt(2) ?

Answer 9

nada

Answer 10

well i cant find anything wrong with my maths... @exp have i made an error? i am quite tired

Answer 11

Answer 12

let's see.

Answer 13

Area will be = absin U
11 = 5*1/sqrt(2) b
b = 11 * 1.41 / 5

Answer 14

need to find a though. i messed up the question.
