5 What is the area of a triangle with a base of
2
mm and a height of 10 mm?
o 8 7 4 mm²
O 13mm?
O 16 mm
261 mm

13⅛mm²

Step-by-step explanation:

Area = ½×base×height

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

6mm^3 or .6cm^3

      216

6     6   6

factor trees are nice.
