These words are point, line and plane, and are referred to as the "three undefined terms of geometry.
They are undefined because they cannot be defined by using other figures.
Answer:

Step-by-step explanation:

means inverse.
Find the inverse of the function.

Replace y with and vice versa.

Solve for y

The inverse function is

The percent increase from $1.80 to $2.07 is 15%.
2.07 / 1.80 = 1.15 - 1 = 15% increase.
If you were trying to find how much $1.80 of $2.07 was in percentage, then here you go:
1.80 * 100 (out of 100%) = 180
180 / 2.07 = 86.95
86.95%
The answer is going to be
X=20
Z = 66
Directions: first find x in its triangle
then y in that.
Then subtract them from 180 degrees for smallest one.
