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
To evaluate the answer of Harry:
8-(2+5)8-(2+5)
