Ответ:
∠BAD = 100°
∠ADC = 105°
∠DCB = 50°
∠ABC = 105°
Step-by-step explanation:
∠BAD is given.
∠ADC is supplementary to the 75°, so it is 180-75 = 105°
∠DCB is 50° just like its opposite angle
The sum of all angles in a quadrilateral must be 360, so ∠ABC = 360-100-105-50 = 105.
Ответ:
Angle ADC = 75 degrees (vertically opposite)
Angle DCB = 130 ( 180-50= 130, angles in a straight line add up to 180 degrees)
Angle CBA=
75+75 = 150
360-150 = 210 (angles around a point add up to 360 degrees)
210/2= 105 (divide by two to find the size of one angle)
So,
105+100+50 = 255
Angles inside a quadrilateral add up to 360
360-255= 105
Angle CBA =105
Ответ:
C
Step-by-step explanation:
It is exponential growth and will eventually have a much higher balance
if i plug in for an example 2 in for x B starts of higher. When i put in 10 it shows that after 10 A is actually higher. This is why the answer is c
