Answer:
36°
Step-by-step explanation:
BY bisects angle B, which has a measure of 72°. That means angles 3 and 4 are each half of 72°, or 36°.
m∠4 = 36°
Currently the denominator is

. If you want to move those up so they sit with the numerator, then what you have to do is make the exponents negative. You make a negative exponent positive by moving it under a 1; undo that process to make the exponents negative. If we do that, then the expression would be
Answer:
19a - 6
Step-by-step explanation:
For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

Where:
m: It's the slope
b: It is the cut-off point with the y axis

We have the following points:

Substituting the values:
Thus, the line is of the form:

We substitute one of the points and find "b":

Finally we have to:

Answer:
The equation es
