Answer:
go everything youve learnt from grade 3 come right up
Step-by-step explanation:
sometimes its knowing the simply formulas thatll get you through
It is C because a straight line is 180 degrees, eliminating A. That being said, the “bigger angle” is 12x-30 because it is obtuse. B and D are both acute, while C is obtuse. You can also find the answer by finding x as in the equation 3x+(12x-30)=180. By simplification, x=14. So, plugging it in, 12(14)-30=138.
Answer:
(0,1) (-1,1)
Step-by-step explanation:
Answer:
n=48
Step-by-step explanation:
- add 48 to both sides to get rid of it
- 43+5=48
- n=48
Answer:
7-8i
Step-by-step explanation:
to find as complex conjugate, simply change the sign of the imaginary pert (the part with the i). this means that is either goes from positive to negetive or from negetive to positive
as as general rule,the complex conjugate of a +bi is a-bi
