In figura alaturata, ABC este un triunghi dreptunghic, unghiul A = 90*, iar AD perp. Pe BC, cu D E BC. Daca BD = 16 m si CD = 9 m, aria triunghiului ABC este; a) 150 m ^2; b) 144 m ^2; c) 25 m ^2; d) 250 m ^2.

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.

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 correct answer is 1: 2

step-by-step explanation:
