To solve this problem, let's first start with a sketch.
00:04
That allows us to see what the triangle looks like, what we know, and what we need.
00:09
The first thing we are given is an angle c of 68 .5 degrees.
00:17
I know side c, which will be opposite the angle on the triangle, is 258 centimeters.
00:26
And side b is 386 centimeters.
00:31
Well, if b is on that side, that means that angle b is somewhere along the bottom of my triangle, and angle a is at the top.
00:40
Now, our given angle is acute, which means i have either zero, one, or two triangles.
00:47
To determine how many triangles we're looking at, let's start by looking at the height, the distance between angle a and the line b .c...
