Multiply both the top and the bottom by (4-3i) to eliminate i in the denominator:
10(4-3i)/(4+3i)(4-3i)=(40-30i)/[4²-(3i)²]=(40-30i)/25
reduce: (8-6i)/5
a=8, b=5, c=6, d=5
Use cosine.

We have:
adjacent = 9cm and hypotenuse = 17 cm

Answer:
$30 per Ticket
Step-by-step explanation:
There are 3 friends coming along you so that means you have to divide one number by 3. You have a $20 coupon so that meant you had to subtract 20 from 120. <em><u>20-120=100.</u></em>
Now, you have to divide 100 by the 3 friends then add 5 to each number.
<em><u>3 divided by 100=25+5=30</u></em>
<u>So, $30 is your answer</u>

Answer:
The distance of the overpass above the ground is approximately 26.795 ft
Step-by-step explanation:
The parameters given are;
The distance from the overpass the engineer stands before determining the angle of elevation of the overpass from his standing point = 100 ft
The angle of elevation of the overpass as determined by the engineer from 100 ft = 15°
By trigonometric ratios, we have;

The opposite side to the 15° angle of elevation in the above case is the distance of the overpass above the ground
The opposite side to the 15° is the distance of the engineer from the base of the overpass
Therefore;
Tan(15°) the height of the overpass=
length

The distance of the overpass above the ground = 100 × tan (15°) ≈ 26.795 ft.
