Answer:
Given : s||t
Exterior sides in opposite rays : ∠5 and ∠7 are supplementary
Definition of supplementary angles : m∠5 + m∠7 = 180°
If lines are ||, corresponding angles are equal : m∠1 = m∠5
Substitution : m∠1 + m∠7 = 180°
Answer:
Step-by-step explanation:
Given
varies directly with 
This means
∝
This can be written as:
where 
is the constant of proportionality.
We know that when 
then 
. Using this we can find value of .
so, we have
Dividing both sides by 8 to isolate .
∴ 
when 
then will be
∴ 
(Answer)

Step-by-step explanation:
Answer:
B = 135
Step-by-step explanation:
An octagon has 8 equal sides, and in total is 1080 degrees. Each angle is 135 degrees which adds up to 1080. Or:
135 × 8 = 1080.
Hope this helped.
Negative x positive = negative
Negative x negative = positive
-4 x 8 = -32
-4 x -1 = 4
-4 x -5 = 20
-4 x 9 = -36
Answer: |-32 4 20 -36|
