Convert the angle in degrees to radians. Express your answer as a multiple of π.

Elena L [17]

Converting 25 degrees to radians:

180° = π radians.

1° = π/180 radians.

25° = (π/180 radians) * 25

= (25/180) * π radians.

Leaving the answer in terms of π, 25/180 = 5/36

= (25/180) * π radians = (5/36)π radians or ≈ 0.1389π radians.

Therefore 25° = (5/36)π radians or ≈ 0.1389π radians

I hope this explains it.

I think why you did not get it was because you did not leave your answer in terms of π or as a multiple of π, so as a multiple of π our answer is:

= (5/36)π radians or ≈ 0.1389π radians

Write the equation of a line passing through -1,4 and perpendicular to x+2y=11

Sophie [7]

Y=2x+6
gradient is found from the formula,
$\frac{ - 1}{ - \frac{1}{2} } = 2$
y intercept is found by subbing the values of (-1,4) into the equation y=2x+c
