I got this. Bottom of the triangle. that flat line is 180 degrees. you have an angle of 120, leaving an angle of 60. if you look at the top, that angle matches the other. so you have 65 degrees on one side, and 60 on the other. so 180-65-60=55. so X=55
Answer:
100°
Step-by-step explanation:
the total of all angles around O on one side of AD is 180° (as that would represent a half-circle).
and the sum of the arc angles AB + BC + CD covers the whole 180°.
so, we have
180 = 55 + BC + 25
180 = 80 + BC
BC = 100°
12 miles in 48 minutes
12/48 or 1/4 miles per minute
Times 60 is 15 miles per hour
Yea, there's a formula :
radians = degrees × π / 180°
