Answer:
use the distance formula you can find it on the net
I need a picture to solve this problem...
This is the answer, attached below. :)
59.4cm
Use Pythagorean theorem to find the diagonal (^ means exponent)
a^2 + b^2 = c^2
42^2 + 42^2= c^2
1764+1764=c^2
3528=c^2
square root both sides
c= 59.39696962
round and you get 59.4 cm
Sin 167 = 0.22495
cos 107 = -0.29237
cos 167 = -0.97437
sin 107 = 0.95630
(sin 167)(cos 107) - (cos 167)(sin 107)
(0.22495)(-0.29237) - ( -0.97437)(0.95630)
= 0.86602
hope this helps :)
