Given the following diagram

Compute the following:

 

(1) Deflection angle at L from W to B

235°23’45” - 180°00’00” = 55°23’45” = 55°23’45” L

 

(2) Interior angle at B

180°00’00” - 130°28’50” = 49°31’10”

 

(3) Angle right at S from P to W

180°00’00” + 84°31’35” = 264°31’35”

 

(4) Interior angle at W

Total angle sum = (n-2) x 180°00’00” = (5-2) x 180°00’00” = 540°00’00”

 

Point

Interior Angle

L

235°23’45”

B

180°00’00 - 130°28’50” = 49°31’10”

P

360°00’00” - 269°06’30” = 90°53’30”

S

180°00’00” - 84°31’35” = 95°28’25”

 

Sum = 471°16’50”

Angle W = 540°00’00” - 471°16’50” = 68°43’10”
