Answer:
sum of the interior angles x and y gives the exterior angle z
(4n-18)°+(n+8)°=(133-6n)°
4n°-18°+n°+8°=133°-6n°
4n°+n°-18°+8°=133°-6n°
5n°-10°=133°-6n°
5n°+6n°=133°+10°
11n°=143°
11°n/11°=143°/11°
n=13
exterior angle=133-6×13
=133-78
=55

Answer:
350km
Step-by-step explanation:
If a map has a scale of 1: 500000, then 1 cm on the map is 500000 cm
So 7 cm on the map is 35000000 cm = 350 km
Answer: M= slope
M= -1/5
Step-by-step explanation:
M= the change in y over the change in x so you would do 1-4 over 13-(-2) which gives you -3 over 15 which is simplified to give you the answer which is -1/5.
Answer:
If you are doing subtraction with fractions you need to make a common denominator and subtract the numerators from each other
ex. 1/2 - 1/3
make a common denominator (or find the least common multiple)
3/6 - 2/6
subtract the numerators
take 2 from 3 and put that on top.
Solution 1/2-1/3= 3/6-2/6= 1/6
