Answer:
Can is gonna be 120 and cba is gonna be 30
Step-by-step explanation:
Use 180 - 60 you will get 120 and the sum degree for a triangle is 180, use 180-60-90 you will get an answer for cba
m∠CAD = 120°
m∠CBA = 30°
b. these codes are equal volume
Sum of opposite angles are supplementary,
x + 60 + 3x = 180
4x + 60 = 180
4x = 180 - 60
4x = 120
x = 120 / 4
x = 30
60°
∠ABC-∠CBD=∠1
