Point M is 6cm from the plane. The angle between the oblique drawn from point M to the plane is 45 degrees. Find the length of the oblique.
Let’s draw a perpendicular to a straight line from point M (its length is 6 cm by condition), we get a right-angled triangle, because. the angle between the straight line and the oblique is 45 degrees, then the projection of the oblique is equal to the perpendicular is 6 cm, => the oblique is √6 ^ 2 + 6 ^ 2 = √36 + 36 = √72 = 6√2 cm.
Answer: 6√2 cm.
