Okay, so we have a triangle a, b, c, and we have that b, c equals 10.
00:08
So from b to c, we're 10, and then a to b is 16.
00:13
All right, and what we want to know is to the nearest tenth of a degree, what is the measure of the largest acute angle in the triangle? so that means it's either going to be angle b or angle a.
00:27
And let's figure out one of those angles first.
00:30
It doesn't matter which one.
00:31
Let's find a.
00:32
So the information i have with a is i have the opposite side is 10.
00:38
I have the hypotenuse is 16.
00:42
And if i have an opposite and a hypotenuse, i want to use sign.
00:46
So we'll use sign of angle a is equal to 10 over 16.
00:53
And to find a, i need to do the inverse sign of 10 over 16...
