Answer:
x = 129°
Step-by-step explanation:
∠ ABD and ∠ DBC are a linear pair and sum to 180° , then
y + ∠ DBC = 180°
107° + ∠ DBC = 180° ( subtract 107° from both sides )
∠ DBC = 73°
the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles , then
x = ∠ DBC + z = 73° + 56° = 129°
Answer:
103.96
Step-by-step explanation:
The answer is 939.44 - 835. 48
we can do like: 939.44 - 835. 48 = 103.96 ( 938 -835 = 103 and 144 - 48 = 96).
Have a good day
