Answer:
x= ~8.69
solve with law of sine:
law of sine essentially states that
(side length)/(sine of opposite angle) are in the same ratio as another (side length)/ (sine of its opposite angle)
right angles =90 degrees
line QS is opposite to angle R
so
QS/ (sin 90)
9/ (sin 90)
line RS is opposite to angle Q
measure of angle Q= 75 degrees
RS/ (sin 75)
x/ sin (75) RS is x
and these ratios are equal according to law of sine
9/ (sin 90)= x/ sin (75)
sin 90=1
sin 75 = approx ~0.9659
4th decimal place for accuracy, will round more later
9/ (sin 90)= x/ sin (75)
9/ 1= x/ 0.9659
9= x/ 0.9659
x=8.6931
round to nearest tenth
8.6931
~8.69
hope this helps !!
Step-by-step explanation:
Angle C must = [180 - 73 - 57 ] = [180 - 130] = 50°
And using rhw Law if Sines, we have.....
AB/sin C = AC/sin B → 24/sin(50) = AC/sin(73) → AC = 24*sin(73)/sin(50) = about 29.96 in
Answer:
8 + 4i
Step-by-step explanation:
Put corresponding terms above each other and subtract in the usual way.
z = 3 + 5i
<u> w = -5 + i
</u>
z - w = 8 + 4i: 3 - (-5} = 8; 5i - 1i = 4
i
