Answer:
1. 360
2. Yes because in a regular hexagon all angles are congruent so the exterior angles are as well
3. (i) 60 (ii) 120
4.
(i) 1. 360 2. Yes because in a regular octagon all angles are congruent so the exterior angles are as well 3. (i) 45 (ii) 135
(ii) 1. 360 2. Yes because in a regular 20-gon all angles are congruent so the exterior angles are as well 3. (i) 18 (ii) 162
Step-by-step explanation:
Works for each polygon
1. First take the number of sides and subtract it by 2 then multibly that by 180
6-2=4x180=720
Then divide by the number of angles and subrtact that number by 180 to find the measure of one exterior angle
720/6=120
180-120=60
Then multiply by the number of exterior angles
60x6=360
2. Regular polygons always have equal angles so the exterior angles are as well
3. Put in your numbers from earlier
(i) 60 (ii)120
Hope this helps! :)

Answer:
66) P = 38m
67) P = 32.7m
Step-by-step explanation:
Perimeter of triangle
P = a + b + c
P = 8 + 16 + 14
P = 38m
Perimeter of trapezoid
P = a + b + c + d
P = 6.4 + 13.6 + 6 + 6.7
P = 32.7
Answer:
8!
Step-by-step explanation:
I'm sure you're still really smart, you just don't understand it :)
Those two bars mean the absolute value of whatever's inside of them. Absolute value is always positive, so if you had 34 inside of the bars, it would still be positive 34.
Now that we know what those bars mean, the expression is really this:
1 + 7
I'm sure you can solve that :)
