For this case we have the following equation:

We must replace the following value in the equation:

Substituting we have:

Simplifying the given expression we have:

Then, using logarithm properties in base 10, we can rewrite the expression:

Finally, making the product, the result is:
Answer:
option 4
Given:
In a right angle triangle θ is an acute angle and
.
To find:
The value of
.
Solution:
In a right angle triangle,

We have,

It means the ratio of perpendicular to base is 3:5. Let 3x be the perpendicular and 5x be the base.
By using Pythagoras theorem,





In a right angle triangle,



Therefore, the value of
is
.
First, you want to get x by itself on one side. We write the equation as

. Since 14 is being subtracted from

, we add it to both sides to cancel it out,

or

.
Your answer would be D.
-7n-21-8-64n distributive property
-7n-64n-29 commutative property
-51n-29 combine like terms
Y=|x-7|-9 because up seven and down nine
