Step-by-step explanation:
Answer:
Step-by-step explanation:
recall law of Sines :) the same as before Sin(A) /a = Sin(B) / b
[ when you see it a lot.. you'll remember it :D ]
for this problem Z =A=123 and a = 30
Y=B and b =14
Sin(123) / 30 = Sin(B) / 14
14 * 0.0279556 = Sin(B)
0.391379 = Sin(B)
arcSin(0.391379 ) = arcSin ( Sin (B) )
23.040 = B
Y = 23.0°
are you seeing how to do these? so you could on a test?
The complex conjugate of 13-21i is 1.3+ 2i.
In general the conjugate of a+bi is a - bi
and the conjugate of a-bi is a + bi
25% is the percent increase
