3.643 x 10^3
move the decimal in between the first and second number
However many times you move the decimal, that is you exponent.
Answer:
Below in bold.
Step-by-step explanation:
b.
If we drop a perpendicular line from B to AC and mark the point D on AC, we have 2 right triangles, with AD = DC = 16 cm.
So tan O = BD/16 = 15/8
BD = (16*15)/8
= 2*15
= 30.
So the area of triangle ABC = 16*30
= 480 cm^2.
In my opinion, i round up until i can no longer round up. But my guess is 103. Please correct me if I'm wrong. :)
