Convert the angle to a decimal in degrees <br> 60 degree 19 ‘39”
7nadin3 [17]

bearing in mind that there are 60 minutes in 1 degree, and 60 seconds in 1 minute.

60°19'39"

so 39 seconds is really 39/60 minutes, or 0.65 minutes

so 19'39" is really 19.65'.

since there are 60 minutes in 1 degree, then 19.65' is really 19.65/60 degrees, or 0.3275°.

60°19'39" is then 60.3275°.

Geometry help with number 18!
lora16 [44]
BE is parallel to CD, therefore, m∠BEC=m∠ECD, therefore mBC=mDE
BE is the diameter, so Arc BE is 180 degree
mBC+mCD+mDE=180
replace mCD with 3mBC, and replace mDE with mBC: mBC+3mBC+mBC=180
5mBC=180
mBC=180/5=36
mCD=3mBC=3*36=108
the inscirbed angle m∠ECD= the measure of arc DE=36
