Answer:
Step-by-step explanation:
10x + 8y = -18
-8x - 8y = 24
2x = 6
x = 3
8(3) + 8y = -24
24 + 8y = -24
8y = -48
y = -6
(3, -6)
To find this question's answer, we need to know that sum of the exterior angles of any given polygon is 360°. This is default and non-changeable.
Now we know that the sum of all exterior angles is 360°, the question says that one angle is equal to 36°.
When we divide them we get:

So, we found that there are 10 exterior angles.
Answer:
m∠4 = 40°
Step-by-step explanation:
Using the vertical angle theorem we can find that...
m∠6 ≅ m∠7


Using this, we know that angle 6 and 8 are supplementary so...
m∠6 + m∠8 = 180°
140° + m∠8 = 180°
m∠8 = 40°
Then, we can use the corresponding angle theorem to find that...
m∠8 ≅ m∠4
m∠4 = 40°
