Step-by-step explanation:
Use Sine rule.
Angle A + angle B + angle C = 180 (sum of angles in triangle)
Angle A + 90 + 42 = 180
Angle A + 132 = 180
Angle A = 180 - 132
= 48
Answer:
B.) It is the product of the initial amount and the additional amount after d days.
Step-by-step explanation:
You multiply in the problem to get your answer.
We have A number of apples, each purchased at 15 cents.
We can, thus, calculate the total cost of apples as follows:
Total cost of apples = 15A cents
We have B number of bananas, each purchased at 10 cents.
We can, thus, calculate the total cost of bananas as follows:
Total cost of bananas = 10B cents
Now, the total cost of purchases can be calculated by adding the amount paid for both types (apples and bananas) as follows:
Total cost = cost of apples + cost of bananas = 15A + 10B cents
You would have the square root symbol (called a radical) over the number 72. But if you mean to simplify it, you can keep in mind that 9 x 3 = 72 and the square root of 9 is 3, so then your answer would be
3(radical)3
Hope that's not too confusing!
