Answer:
Check the intersecting lines with the corner of a piece of paper to ensure the lines create 90° angles. Check the distance along the lines at several places with a compass to ensure they are the same length.
Answer:
50
Step-by-step explanation:
first angle = x
second angle = x+30
third angle = 4x
x + (x+30) + 4x = 180
6x + 30 = 180
6x = 180 - 30
6x = 150
x = 150:6
x = 50
Answer:
B
Step-by-step explanation:
We can figure out the initial value and base of an exponential function if the function is written in the form
where
a is the initial value, and
b is the base
<u>Note:</u> a ≠ 0 and b ≠ 1
Our equation given can be written in this form by writing it like 
Thus, this is an <em>exponential function</em>. The initial value is 1 and the base is 5.
The correct answer is B
I’m not a good math person but I think your pretty right.
