Answer:
SAS postulate
Step-by-step explanation:
AD (common)
AC = BD (both are diameters)
Angle COD = Ange AOD (vertically opposite angles)
Angle CAD = Angle BAD (angle on the circumference is half the angle at the centre)
Therefore, ABD and DCA are congruent by SAS postulate
Answer:
sin70°
Step-by-step explanation:
Given sin110° where 110° is an obtuse angle in the second quadrant.
The related acute angle in the first quadrant is 180° - 110° = 70°
Thus
sin110° = sin70°
Answer:
the answer is A.
Step-by-step explanation:
The slope is 2/3 and the y intercept if you need it is -3
Answer:
Altura = 20,000 cm
Step-by-step explanation:
V = (pi x r^2 x a)/3
1.696.464 = (3.14 x 9^2 x a) / 3
1.696.464 = 84,82 altura
1.696.464 / 84,82 = altura
a = 20,000cm
