See the figure attached to better understand the problem
we now that
in the triangle ABC
tan alfa=126/120----------> 1.05
alfa=arctan (1.05)-------> alfa=46.40°
in the triangle ADC
sin alfa=DC/120----------> DC=sin(46.40°)*120---------> DC=86.90 units
the answer is 86.9 units
Answer:
200000
Step-by-step explanation:
I believe that 200000x7000 = 1400000000 (The answer to the China population equation), therefore should be correct. Hope this helped.
Answer:
2nd number is correct
Here's your solution
=> 2p(-3p^2 + 4p - 5)
=> multiple 2p with whole
=>. -6p^3 + 8p^2 - 10p
this is your answer
hope it helps
