It is just asking to find the sum of interior angles
So follow this rule 180(n-2)
180(5-2)
180(3)= 540
So in another words: a+b+c+d+e=540
Answer:
Vertex - (2,1)
minimum
Step-by-step explanation:
minimum y≥1
Do not go to that link it is a virus and if you go to “goggle” and press the camera icon on the top right and take a picture of the question you should get the answer there
The tangent of the angle is
... tan(α) = ay/ax = -8.6/6.1
Then the angle (measured CCW from +x) is
... α = arctan(-86/61) ≈ 305°
