The answer is d because he buys them for .3 and sells them for 1 so 100-30=70=.7 and then it costs him 3 to advertise so you subtract three
<HBF = <GBF + <HBG
but
<GBF = <CBD (vertical angles)
< HBG = <DBE (vertical angles)
so
<HBF = <CBD + <DBE
Answer
A. <CBD + <DBE = <HBF
Slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept. This makes the equation of our line y = 2x+0 or y = 2x.
We are required to find the cosine and tangent of 60°. Here we use an equilateral triangle whose side is 2 units, the height of the triangle by Pythagorean theorem will be √3 units, the base of the right angle triangle formed by bisection of the base will be 1 unit.
thus:
tan θ=opposite /adjacent
opposite= √3
adjacent=1
hence:
tan 60=√3/1=√3
cos θ=adjacent/ hypotenuse
adjacent=1
hypotenuse=2
thus
cos 60=1/2
