Answer:
The exterior angle of 60° is 120°. The exterior angle of 65° is 115°. The exterior angle of 55° is 125°.
Step-by-step explanation:
The sum of the interior angle and the exterior angle is 180°. So you can subtract each interior angle from 180 and get the exterior angle.
180° - 60° = 120°
180° - 65° = 115°
180° - 55° = 125°
This is because you can imagine the lines of the triangle extending beyond the triangle. Then you can see where the other angles are. Hope this makes sense!
Answer:
500
Step-by-step explanation:
1/10 of 5000 is 500.
500 x 10 = 5000
Answer:
50th term is 164
Step-by-step explanation:
a(n) = 17 + 3(n - 1)
a(50) = 17 + 3(50-1)
a(50) = 17 + 3(49)
a(50) = 17 + 147
a(50) = 164
Answer:
If you want me to solve for b then
b ≤ −

The equation of a circle is defined by:
(x-h)^2+(y-k)^2=r^2
Where (h,k) s the center and r is the radius.
We can translate the word problem into (x+2)^2+(y-8)^2=16
