This storyboard was created with
students,so today I wil give you some questions of trigonometry
the trigonometric ratios which are sina = opp/hypcos a = adj/hyp...
no! its so easy
mam this chapter is so tough for me
Mam ,I Dont know
ac=25, So sin A = 7/25 & cos A = 24/25
if AB= 24cm,BC=7cm.then determine: sin A & cos A
Yep, Its true
cos A is the abbreviation used for cosine of angle A ...True or False ?
NOO! Its true
Mam ,I Don't know
1-Tan2 45/1+ Tan2 45 equals to ??
A tower stands vertically on the ground from a point on the ground which is 15m away from the tower the angle of elevation of the top of a tower is found to be 60 degree. fin the height of tower.
Tan 60 = h /15 root3=h/15so, H = 15root3
