Answer:
Top right answer
Step-by-step explanation:
He added the -x to 4x when he should have subtracted.
<u>Given </u>that the length of the hypotenuse is 8 and the angle is 42°
The length of the one leg of the triangle is x.
We need to determine the value of x.
<u>Value of x:</u>
The value of x can be determined using the trigonometric ratio.
Thus, we have;

Substituting the values, we get;

Multiplying both sides of the equation by 8, we get;

Simplifying, we get;


Therefore, the value of x is 5.35(app.)
Hence, Option A is the correct answer.
Answer:
- $450,000 at 10%
- $50,000 at 9%
Step-by-step explanation:
Let x represent the amount invested at 10%. Then the total interest earned per year is ...
0.10x + 0.09(500,000-x) = 49,500
0.01x = 49500 -45000
x = 4500/0.01 = 450,000
$450,000 was deposited in the 10% account; $50,000 was deposited in the 9% account.
