Answer:
1. In triangle ABC,
AC = a = 10, BC =b= 7 and ∠ C = 90°
By cosine law,
Now, by the law of sine,
2. In triangle ABC,
∠B = 30°, AB=c=10 and ∠C = 90°
∠A = 180°-(30+90)°=60°
⇒ 
By Pythagoras,
⇒ 
Answer:
i believe that it is 96 hours
Step-by-step explanation:
This is a subtraction problem so subtract 3/4 from 7/8 (7/8 - 3/4). First you have to make them both have the least common denominator. That is 8. So multiply both the numerator and denominator or 3/4 by 2. 3 x 2= 6 and 4 x 2= 8. New fraction is 6/8. Now solve problem again with new fraction. 7/8 - 6/8= 1/8. Your answer is 1/8
Answer:
1,803.268
Step-by-step explanation:
