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°
For math- The difference between a value of a variable and another variable which usually ends up to be the variables mean
Answer:

Step-by-step explanation:
5-1+2=3
Answer:
y=2/5x-15
Step-by-step explanation:
y-y=m(x-x¹)
y-(-11)=2/5(x-10)
y+11=2/5x-4
-11 -11
y=2/5x-15
