<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.

Step-by-step explanation:
Answer:
1) x = 6.6.
2) x = 6.1.
Step-by-step explanation:
1) In this triangle, the hypotenuse is given, which is 8 units, and the angle is given, which is 35 degrees. The base is unknown. To find the base, following ratio will be used:
cos θ = Base/Hypotenuse.
cos 35 = x/8.
x = 8*cos 35.
x = 6.6 units (to the nearest tenth)!!!
2) In this triangle, the base is given by 12, and the angle is given by 27 degrees. The perpendicular is unknown. To find the perpendicular in this case, tangent formula will be used:
tan θ = Perpendicular/Base
tan 27 = x/12.
x = 12*tan 27.
x = 6.1 units (to the nearest tenth)!!!
