Hi guest!

So to start, you have to multiply the denominator by the conjugate.

\(\frac{2-3i}{-1+5i}\cdot\frac{-1-5i}{-1-5i}\)= \(\frac{-17-7i}{26}\)

The answer is \(\frac{-17-7i}{26}\)

I hope this helped you, guest!

Let me know if you have any questions!

a) 90-24-24=42. \(x=42^{\circ}\)

(i) \(\angle q\) also has a size of \(135^{\circ}\) because they are vertical angles, and vertical angles are congruent.

(ii) \(p+q+r=360-135=\boxed{225^{\circ}}\)

I hope this helped you, guest!

If you have any questions, don't hesitate to ask!

The answer is 89.050 becuase 

   84.7128

+   4.337

---------------

   89.0498

The rule of adding for sig figs is that since 4.337 has 3 digits after the decimal point, the sum has to have 3 digits after the decimal point also. 

So, we can disregard the last 8 and we get 89.049. Now, we round it and since 8>5, and 9>5, the final answer is 89.050.

wow! thank you so much geno! that makes so much more sense now!

Yeah, 20 is right, but I'm confused as to why...

wow!, thank you so much HELPMEEEE! 

Yes!! It was correct, and the solution was on point!
