What is the length of the support AB?

 cos 45 degrees by 7
 7 tan 45°
 7 by sin 45 degrees
 7 cos 45°

rishavraj · Answer

see the projection of AB would be AB cos45 and AB sin 45
and u can see ABsin 45 = 7

ddcamp · Answer

Remember the trig relationships are:
$$\sin = \frac{opposite}{hypotenuse} \ \cos = \frac{adjacent}{hypotenuse} \ \tan = \frac{opposite}{adjacent}$$

If this is your triangle, what sides do you have? What side are you looking for?
