Answer:
- Rational Number
- Real numbers
Step-by-step explanation:
Since DB bisects ∠ABC and ∠ABC= ∠ABD + ∠DBC, then
∠ABD = ∠DBC, that is
4x = x + 36 ( subtract x from both sides )
3x = 36 ( divide both sides by 3 )
x = 12
∠ABD = 4x = 4× 12 = 48°
∠DBC= x + 36 = 12 + 36 = 48°
∠ABC = 48° + 48° = 96°
Thus statement A is FALSE
statement B is TRUE
statement C is TRUE
Answer:the measure of angle 6 is 60 degrees.
Step-by-step explanation:
The two blue lines are straight and parallel lines. The sum of the angles on a straight line is 180 degrees. Angle 5 and angle 6 are on a straight line. Therefore
Angle 5 + angle 6 = 180
If angle 5 is 120 degrees, then
Angle 6 = 180 - 120 = 60 degrees.
