oposite angle is equal
other angles are supplementary (supplementary means add to 180, and a straight line=180 so if you look at 2 lines intersecting and think for a little bit, you wiill see why)
oposite angle=30
other angle is adds to 180
30+other=180
subtract 30
other=150
other is oposite other other
other=other other
150=other other
angles are
150,30,150
Here are a few rules you need to know for this equation:
- Multiplying exponents of the same base:

- Dividing exponents of the same base:

- Turning a negative exponent to a positive one:

So this is our algebraic expression: 
Firstly, multiply 3^-4 and 3^2: 
Next, divide:

Next, turn the negative exponent into a positive one: 
<u>Your final answer is 3/2, or 1.5.</u>
