Hila is asked to draw an equilateral triangle ABC. First, she draws a horizontal line segment that she labels AB, and it has a length of 8 cm. What could her next step be? Use a protractor to measure a 60° angle that has A as its vertex. Use a protractor to measure a 60° angle that has the new point C as its vertex. Draw another 8 cm segment up from A to a new point C. Draw another 8 cm segment up from B to a new point C.

.5 lb

step-by-step explanation:

12 in / 6 in =2 in

.25 x 2 = .5 lb

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

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
