geometry help!?

Question

okay it says...

m m I know you have to add both angles together to make 180 degrees...but i don't know how to get that 15'+___...

m Find m
if anyone knows how to do this
please help!

Answer 1

60 minutes in 1 degree.

So...
180 - 37 d 15 m
= 179 d 60 m - 37 d 15m
= (179 - 37)d (60 - 15) m
= 142 d, 45 m

If

Answer 2

15' = 15 minutes = 15/60 degrees = 1/4 degree

37 degrees 15' = 37 + 1/4 = 149/4 degrees

m
m
= 571/4 degrees = 142 3/4 degrees

= 142 degrees 45'

b)

m
m
= 26 degrees 44 minutes 13 seconds

since 60 seconds = 1 minute

60 minutes = 1 degree

Answer 3

m m 142 degrees 45 minutes

m Find m

Answer 4

Make sure you know your definitions. Vertical angles (opposite angles formed by intersecting lines) are equal so 179deg + 60'. Now you can do the subtraction:

179deg 60minutes
- 37deg 15minutes

by subtracting like terms to get

142deg 45minutes

Answer 5

Instead of 180 degrees write 179º60´ and substract 37º15
you get 142º45´
I don´t understand the 2nd question but if you have an angle in degrees ex:
53º= 52º59´60´´ so you can operate as before

Answer 6

I believe there are 60' in 1 degree.
