Look at image I attached below.
Step-by-step explanation:
Important points to memorize when finding missing angles like these:
- Two angles directly <u>across</u> from each other, <u>not next to</u>, are equal.
- <u>All</u> angles that are on one side of a straight line add up to 180°, because a straight line has an angle measure of 180°.
- A full spin-around equals 360°.
- <u>All</u> angles in <u>any triangle</u> add up to 180°.
When you know all these important rules, the rest is just a matter of adding and subtracting.
Hi
6 · (x-3) = 30
6(x) + 6(-3) = 30
6x - 18 = 30
6x = 30+18
6x = 48
x = 48/6
x = 8
Log(7x+1) - log(x-2) =1
log[(7x+1) / (x-2)] =1 or log[(7x+1) / (x-2)] =log10 (log10=1)
it means (7x+1) / (x-2) =10
Solving ===> x=7
