Situation about the leaning tower of pizza, pizza, where they change the angle of the building with the ground.
00:08
And so they want to know what is the new distance that this point is from the tip of the building here.
00:15
Now, they have drawn a before and after picture.
00:18
It says before that length of the building, which is 50 .5, and at that point was 4 .25 from the building, from that tip.
00:30
So we can now find the value of theta.
00:33
We're given that this is adjacent.
00:34
This is a hypotenuse.
00:36
So we know the cosine of theta is going to be 4 .25 over 50 .5.
00:43
And so theta is going to be the inverse cosine of that amount.
00:49
So i'm going to go to my calculator here and i'm going to get that value...
