Hello : 
<span>b/a = (3-2i)/(2+i)
      = </span>(3-2i)(2-i)/(2+i)(2-i)
      = (3-2i)(2-i)/(2²-i²) .......i² = -1 
      = (6-3i-4i -2)/5
      =(4 -7i)/5
b/a = (4/5)-(7/5) i

Find the angle of depression
slavikrds [6]

Given:

In triangle ABC, m\angle A=66^\circ, AB=5\text{ mi}.

To find:

The angle of depression from point A to point C.

Solution:

According to angle sum property, the sum of all interior angles of a triangle is 180 degrees.

In triangle ABC,

m\angle A+m\angle B+m\angle C=180^\circ

66^\circ+90^\circ+m\angle C=180^\circ

156^\circ+m\angle C=180^\circ

m\angle C=180^\circ-156^\circ

m\angle C=24^\circ

We know that if a transversal line intersect the two parallel lines, then alternate interior angles are equal. So, the angle of depression from point A to point C is equal to the measure of angle C in triangle ABC.

Therefore, the angle of depression is 24 degrees.

The functions s and t are defined as follows.
soldi70 [24.7K]
-77
You first solve for s(x) by plugging in 5 as the variable
-3*5-4=-19
You then plug the -19 into t(x) and 4*-19-1= -77
