Answer:
34°
Step-by-step explanation:
The angle formed by two tangents is equal to half the difference of the intercepted arcs.
The first intercepted arc, between points A and C, is 146°. This leaves
360-146 = 214° for the second intercepted arc.
The difference between these two is
214-146 = 68°
Dividing this by 2,
68/2 = 34°
Answer:
cos(X+Y) = cos(55+35) = cos(90) = 0
Step-by-step explanation:
cos(X+Y) = cosXcosY - sinXsinY
cos(55+35) = cos(55)cos(35) - sin(55)sin(35)
cos(55+35) = cos(55)cos(35) - cos(90-55)cos(90-35)
cos(55+35) = cos(55)cos(35) - cos(35)cos(55)
cos(55+35) = 0
cos(90) = 0
Answer:
The correct answer is 7.5
Step-by-step explanation:
100x5=500
500÷4=125
125x6=750
750/100=7.5
The answer is 7.5 m
