Answer to Problem 29RP
Measure of angle
Explanation of Solution
Given information: In the given figure a straight line is given where measurement of two angles is given as
Calculation:
We know that sum of all the angles on a straight line add up to
So, here
Converting given angles completely in degrees using DMS(Degree ,minute, second) relation according to which to convert minute(‘) into degree we divide by
Considering
And
Substituting values from (ii) ,(iii) into (i) we get :
Now converting
Minutes
Seconds =
Plugging in values of minutes and seconds in (iv) we get:
