Answer:
The first box should have the formula/quantity should be 100/12 (division) and equal to 8 ⅓. The second box formula/quantity should be always multiply with 12 along with how many feet there is.
Answer:
1
Step-by-step explanation:
Exterior angle is equal to sum of interior opposite angles hence,
req. angle = 80 + 62 = 142
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
