If you're evaluating, then multiply by the conjugate and simplify.
= -1 -i
The answer would be the same even if you divided...and or, wrote it in simplest form.

Answer:

D; x -y = 22

3x + 2y = 246

Step-by-step explanation:

Let us have the bigger number as x and the smaller as y

The difference between the two is 22

Thus, we have it that;

x - y = 22

twice the smaller number; 2(y) added to thrice the larger 3(x) equals 246

3x + 2y = 246

So we have the two equations as;

x -y = 22

3x + 2y = 246

Happy Tuesday! Looking for some help with my geometry.

svetlana [45]

Answer:

cos 59° = x/16
x = 16 cos 59°
x = 8.24

BC is given 23 mi

Maybe AB is needed

AB = √34² + 23² = 41 (rounded)

BC² = AB² - AC²
BC = √(37² - 12²) = 35

Let the angle is x

cos x = 19/20
x = arccos (19/20)
x = 18.2° (rounded)

See attached

Added point D and segments AD and DC to help with calculation

BC² = BD² + DC² = (AB + AD)² + DC²

Find the length of added red segments

AD = AC cos 65° = 14 cos 65° = 5.9
DC = AC sin 65° = 14 sin 65° = 12.7

Now we can find the value of BC

BC² = (19 + 5.9)² + 12.7²
BC = √781.3
BC = 28.0 yd

All calculations are rounded
