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:
1/6
Step-by-step explanation:
On an equal dice? 1/6
There are 6 sides to a dice.
The sum of all the probabilities is 1.
As each side has equal probability, their probability is 1 / number of options = 1/6.
Answer: $117.59
Step-by-step explanation:
Answer:
the least common denominator between 4 and 9 is 36
Step-by-step explanation:
The recursive formula would be:

This is because the first term, a₁, is 10. A recursive rule is dependent upon the term before it (a(n-1)) and the common ratio. The common ratio, or the number that each term is multiplied by, is -8.
