Answer:
A. 280°
Step-by-step explanation:
Look at angles 1 and 2. Together, they form a straight angle. The measure of a straight angle is 180°.
We are told that the measure of <2 is 40°.
Since angles 1 and 2 together measure 180°, then the measure of <1 must be 140° since 180° - 40° = 140°.
Now we have m<1 = 140°.
Angles 1 and 6 are vertical angles. Vertical angles are congruent.
Therefore, m<6 = 140°.
We have m<1 = 140° and m<6 = 140°.
m<1 + m<6 = 140° + 140° = 280°
Answer: A. 280°
Domain goes from left to right. I know that it cant be C or D. My answer is B.
Answer:
y=-1
Step-by-step explanation:
-5y+8=-3y+10
-5y-(-3y)+8=10
-5y+3y=10-8
-2y=2
y=2/-2
y=-1
Answer:
it's not a regular polygon
Step-by-step explanation:
a central angle of a regular polygon is 360/n
360/n=35
n=360/35=10.28
it's not a regular polygon
