Find the area of a triangle with a base length of six units and a height of seven units

A = 21

Step-by-step explanation:

Hello

The triangle area is= (base*height)/2, so

A = (6*7)/2

A = 42/2

A = 21

Remember that a trinagle is the area of half square =D

Best regards

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

the answer is 48m^2!
