Question

(Cos 15 - cos 75) : (sin 75 - sin 15)

Answer 1

Step-by-step explanation:

[cos (90-75)-cos75] :[sin 75 -(sin 90-75)]

(sin 75-cos75)(sin 75-cos 75)

(0)(0)

0

Answer 2

Step-by-step explanation:

(Cos 15°- cos 75°):(sin 75°-sin 15°)

(cos(90°-75°):(sin 75-(sin 90°-75°))

(sin 75°-cos 75°):(sin 75°-cos 75°)

1 :1
