Answer:
b) 105°
d) 130°
Step-by-step explanation:
An external angle has the same measure as the sum of the remote internal angles.
b) ? = 25° +80° = 105°
d) ? = 35° +95° = 130°
_____
This should be fairly obvious if you consider that the adjacent internal angle together with the external angle totals 180°, and the adjacent internal angle together with the other two internal angles totals 180°.
If the two "remote" angles are A and B, and the adjacent internal angle is C, then we have in symbols ...
A + B + C = 180° = ? + C
If we subtract C, then we find ...
A + B = ? . . . . . . the fact we used above

Step-by-step explanation:

22' is 22 minutes
there are 60 minutes in 1 degree, how many in 22? well, the short answer is you divide it by 60, or 22/60 0.37 or thereabouts, so that makes it
121.037 degrees and 36''
36'' is 36 seconds, there are 60 seconds in 1 minute, so in short, just divide it by 60 as well, so 36/60 or 0.6 minutes
so, let us revise above some
121 degrees 22' and 36''
22' and 36'' is 22.6' because 36'' is 0.6'
how much is 22.6' in degrees? well 22.6/60
or about .38
so. 121° 22' 36'' will be 121.38° approximately
