Question

please friends tell me those question

Answer 1

hey mate

here is your answer

360°=400 grade

therefore

315°=400/360*315 grade

=350 grades


if tan theta=5/12

then,let perpendicular be 5x and base be 12x

therefore , hypotenuse is 13x

therefore,sin theta=perpendicular/hypotenuse

=5x/13x

=5/13(answer)



400 grades =2 π radian

150 grades=2π/400*150. radian

=0.75π radians
