Answer:
D=12yrs ANSWER 1: The daughter is 12 years old.
J=4D=4(12yrs)=48yrs ANSWER 2: Mr. James is 48 years old.
CHECK
J-D=36yrs
48yrs-12yrs=36yrs
36yrs=36yrs
Step-by-step explanation:
Step-by-step explanation:
x²y = k, where k is a real constant.
When x = 3.5, y = 8.
=> (3.5)²(8) = k, k = 98.
When y = 8/9,
we have x²(8/9) = (98).
=> x² = 110.25
=> x = 10.5 or x = -10.5.
Since we want the negative value,
the answer is x = -10.5.

Step-by-step explanation:
Hello! I hope you are having a nice day!
We can solve this problem in two steps; solving and theory.
I'll go and start off with the theory part!
Theory
We know that in geometry there are many types of triangles that have various different angles. With that, there are a few special triangles that people have made formulas for, one being a 30, 60, and 90 degree triangle.
The theorem states that the hypotenuse is , the side opposite to 60 degrees is , and the bottom is .
Solving
We can solve this problem in a step, we just need to know what the theorem said and implement it here, since we know the values of the sides of the triangle, we can solve it by finding out the opposite side and applying the theorem rules.
If we look at the graph, we can see that the part of the side opp. of 60 degrees is 4, that means that would be double of 4, which is 8.
Therefore your answer would be:
Cheers!
