240. 30 x 8 = 240, so dividing it would equal 30. So, the answer is 240.
Answer:
angle B is 38 degree
Step-by-step explanation:
In triangle ADC,
finding angle C
angle A + angle C = 110 degree (sum of two interior opposite angles are equal to the exterior angle formed)
46 + angle C = 110
angle C = 110 - 46
angle C = 64 degree
In triangle ABC
finding angle B
angle A + angle B + angle C = 180 degree (sum of interior angles of a triangle)
78 + angle B + 64 = 180
142 + angle B = 180
angle B = 180 - 142
angle B = 38 degree
Answer:
D.
Step-by-step explanation:
The mean is 11,000
Area of circle = πr² = 3.14×4² = 50.24m²
The best approximation is C.
midpoint = ( 
, - 6 )
using the midpoint formula
midpoint = [ 
(4 + 9), (- 10 - 2 )] = ( , - 6)
