We have been given an expression
. We are asked to find the solution to our given expression expressed as scientific notation.
Let us simplify our given expression.
Using exponent property
, we will get:



Now to write our answer in scientific notation, we need our 1st multiple between 1 and 10. So we will rewrite our expression as:



Therefore, our required solution would be
.
Answer: 
Step-by-step explanation:
When two lines cross each other , then the opposite angles are known as vertical angles.
Vertical angles are equal.
Here, ∠A and ∠B are vertical angles.
So, ∠A = ∠B
If
and 
Then , 
Subtract 5x from both sides, we get

Add 11 on both sides, we get

Now , 
Hence, the measure of
