In this question given is angle a equals to 39 .70 degree, angle c equals to 30 .35 degree, and side b equals to 39 .74 meter.
00:17
Here, we have to find the remaining sides and angles.
00:23
We know that some of angles in a triangle is 180 degrees, so a plus b plus c equals to 180 degree.
00:31
From here we will find angle b equals to 180 degree, minus 39.
00:38
70 degree minus 30 .35 degree.
00:41
From solving it, the get angle be equals to 110 degree.
00:52
Now we will find side a by using log signs.
00:57
We can write a upon sine a equals to b upon sign b.
01:06
A equals to b sine a divided by sine b...
