In a friendly game of handball, you hit the ball essentially at ground level and send it toward the wall with a speed of 12m/s at an agle of 20 degrees above the horizontal.

How long does it take for the ball to reach the wall if it is 6.2m away?

How high is the ball when it hits the wall?

How do you think you should start with this problem? How far have you gotten already? Where are you stuck?

Not exactly sure how to do this problem. I tried to use the sign/cos method but it didn't work so I'm pretty much stuck...

I think that cos would be used for the time, and either tan, pythagoras theorem or sin to solve this.

Well, what parts of your triangle do you know? Have you tried to sketch the situation?

The ball would hit the wall at a hight of 2.3 meters in 0.55 seconds.
Does that answer your qustion;)
