<u>Answer:</u>
The value in 3x + 2 = 15 for x using the change of base formula is 0.465 approximately and second option is correct one.
<u>Solution:</u>
Given, expression is
We have to solve the above expression using change of base formula which is given as
Now, let us first apply logarithm for the given expression.
Then given expression turns into as,
By using change of base formula,
x + 2 = 2.4649
x = 2.4649 – 2 = 0.4649
Hence, the value of x is 0.465 approximately and second option is correct one.
First, we are going to use the law of cosines to find the length of the line segment FH:
Next, we are going to use the semi-perimeter formula:
Now that we have the semi-perimeter of our triangle, we can find its area using Heron's formula:
We can conclude that the area of the triangle <span>GHF is 2.7 </span>
