This question we have to solve this right triangle for all these remaining three parameters.
00:05
So angle a is given and definitely c is already 90.
00:08
So angle b can be easily found because angle b then will be 180 minus the sum of remaining two angles which is 90 and 38 .5.
00:20
So this is coming as 180 minus 90 is 90 and 90 minus 38 .5 is 51 .5 degrees.
00:29
So this is the value of angle b.
00:34
Then we have to find the value of a and c.
00:39
So for a, we are going to use tan because tan of angle a will be opposite, which is a over adjacent, which is b.
00:47
Now angle a is already given to us as 38 .5.
00:53
Side a is unknown and side b is 33.
01:00
So if we cross multiply, the value of a comes out as 33 tan of 38 .5.
01:08
So the value of a from here comes out as tan of 38 .5 times 33, which is 26 .25...
