Answer:
100°
Step-by-step explanation:
A triangle is a polygon shape with three sides. Triangles are of different types such as obtuse, scalene, equilateral, isosceles etc.
In triangle ABC:
70° + 50° + ∠C = 180° (sum of angles in a triangle)
120 + ∠C = 180
∠C = 180 - 120
∠C = 60°
Since ∠C is bisected into ∠ACD and ∠BCD, hence:
∠ACD = ∠BCD = ∠C / 2
∠ACD = ∠BCD = 60 / 2
∠ACD = ∠BCD = 30°
In triangle ACD:
∠A + ∠ACD + ∠ADC = 180° (sum of angles in a triangle)
50 + 30 + ∠ADC = 180
∠ADC + 80 = 180
∠ADC = 100°
a)
22 * (1 - 0.25) = 16.50
b)
16.50 * (0.2) = 3.30

white 47.7%,
mulatto (mixed white and black)
43.1%, black 7.6%,
Asian 1.1%,
it is 8.5 x 10^2 because when you times the 10 twice and then multiply it with 8.5 and the decimal moves
5/9
