Answer:





Step-by-step explanation:
Part 1) Find the measure of angle 1
we know that
-----> by supplementary angles

Part 2) Find the measure of angle 2
we know that
-----> by alternate exterior angles
Part 3) Find the measure of angle 3
we know that
-----> by vertical angles
Part 4) Find the measure of angle 4
we know that
------> by corresponding angles
Part 5) Find the measure of angle 5
we know that
-----> by vertical angles
so

Part 6) Find the measure of angle 6
we know that
-----> by supplementary angles
we have

substitute


Answer:
-10
Step-by-step explanation:
Use PEMDAS (Parenthesis, Exponents, Multiplication/Division, Addition/Subtraction)
8 + (-2) · 9
8 - 18
-10
Answer:
x=30
Step-by-step explanation:
Find the value of x that will make A and B parallel
For A & B to be parallel, the interior angles must be supplementary, i.e.
4x+2x = 180
6x=180
x=30
When x=30, the interior angles are 120 and 60 which are supplementary.
