Answer:
(D)
<u>Use the law of sines:</u>
- 13 / sin x = 12 / sin 67°
- sin x = 13 sin 67° / 12
- sin x = 0.997
- x = arcsin (0.997)
- x = 85.6°
(E)
<u>Find the third angle:</u>
<u>Use the las of sines:</u>
- x / sin 61° = 21 / sin 71°
- x = 21 sin 61° / sin 71°
- x = 19.4 cm
Answer:
121
Step-by-step explanation:
we know that
A <u><em>perfect square</em></u> is an integer that is the square of an integer.
In this problem
The integer or base factor is equal to 11
therefore
squared the integer to find out the perfect square

The complex number is given as: 2-8i
So for conjugate, you just flip the sign of the imaginary part:
2+8i will be the answer
