2 answers:
Answer:
Step-by-step explanation:
The distributive property tells us that we must multiply the number that is outside the parentheses by each of the elements inside the parentheses:
the original expression we have is:
Using distributive property (multiplying 8 by each component of the parenthesis):
and then solving the operations we have:

Answer: Angle 2 = 47 degree
Explanation:
Proof that triangle ACB ~ triangle CBD
Angle ABC = Angle CBD (same angle)
If one pair of the angle is the same then the other pair should also be equal because both the triangle are Isosceles.
=> angle ACD = Angle CDB
Therefore, triangle ACB ~ triangle CBD (AA)
=> angle C = Angle A
But angle A = 47 degree
Therefore, Angle C = Angle 2 = 47 degree
