The intersections of 12th St., Constitutional Ave., and Pennsylvania Ave. in Washington, D. C. form a triangle. The Old Post Office is wedged in the 12th St. − Pennsylvania Ave. angle of this triangle. If the 12th St. − Constitutional Ave. angle measures 90°, and the Constitutional Ave. − Pennsylvania Ave. angle measures 30°, what is the measure of the angle the Old Post Office is wedged in?

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2

days of the week

step-by-step explanation:

javier earned more money then kyle, so that won't always be a constant term, but the days of the week do not change so that term is always constant.

edit: i meant
