Pentagons ABCDF and JKLMN below are similar, but not necessarily drawn to scale. Find the values of x and y.

A
x = 40 mm, y = 150 mm

B
x = 1.6 mm, y = 6 mm

C
x = 40 mm, y = 6 mm

D
x = 24 mm, y = 14 mm

Guys i really need or i have to stay late up night

What expression is equivalent to log3(x+4)

Which sum or difference identity would you use to verify that cos (180° - q) = -cos q? a.) sin (a -b) = sin a cos b – cos a sin b b.) cos (a -b) = cos a cos b – sin a sin b c.) cos (a -b) = cos a cosb + sin a sin b d.) sin (a + b) = sin a cos b + cos a sin b
