Answer:
measure of two unknown angles are 35.7° and 75.4°
measure of one unknown side is 16.6 inches
Step-by-step explanation:
i used law of sines to find the angle opposite 10 inch side
sin 68.9/16 = sinФ/10
Ф = 35.7°
then is added 35.7 and 68.9 and subtracted the sum from 180° to get the measure of the third angle, 75.4°
i used law of sines again to find the measure of the third side
sin 68.9/16 = sin 75.4/x
x = 16.59
1. b
2. c
3. c
(x+3)^2=147
You can solve this using proportion.
5 = 4
7 = ?
7(4)/5= 5.6
