In finding true angle (satellite station) reduction to center, then which formula is used? Please tell me.

Include angle b/w ABC = 108 - 146°30" + 68°30" = 102°.

The Azimuth of a line AB is 114 and the angle ABC 126°30'20". Calculate the Bearing of BC?

Please answer this.

BB of AB + FB of BC.
BB of AB is 180-146.30 = 33.30,
FB of BC is 68.30.
So, 33.30 + 68.30 = 102.

Applying formula..Included angle = f.b of next line - b.b of previous line.
= f.b of BC - b.b of AB.
= 68.30 - 146.30.
= 78.
+180 = 102.

AB = 107*15'.
BC= 22*00'.
AB-BC= 107*15-22*00= 85*15'.

Included angle ABC= 180*-85*15'= 94*45'.

180°-146°30°= 33°30°00°.

So,
<ABC = 68°30°+ 33°30°00° = 102°.

As per my knowledge, Interior angle = BB of AB - FB of BC.

Are interior angle and included angle same.

Guys take as simple.

∠ABC = F.B of BC - B.B of AB
= 68°30'- (146°30'+180°)
= -258°.
= -258° + 360°.
= 102°.

Hope it will help!
