Answer:
ответ j = 10
Step-by-step explanation:
{3π/4 , 7π/4}
2 + Tanθ = 1
tan θ = 1 -2
Tanθ = -1
θ = 3π/4 and 7π/4
See the image below for answer:)
Linear pair is two adjacent angles whose non-common side from opposite rays. the line through points A., B and C is straight line. if two angles from a linear pair the angle are supplementary.
