Given the following diagram, enter the required information.

m bxa = 30° 20', m cxb = 40° 35'
m cxa __° __'

The length of the ∠CXA  is  70° 55'

Step-by-step explanation:

Given = ∠BXA = 30° 20', ∠CXB = 40° 35'

To find = ∠CXA =?

Solution:

∠BXA  + ∠CXB = ∠CXA  (from the diagram)

30° 20' + 40° 35' = ∠CXA

∠CXA  = 70° 55'
