Question

Given the following diagram, enter the required information.

m BXA = 30° 20', m CXB = 40° 35'
m CXA __° __'

Answer 1

m(CXA) = m(BXA) + m(CXB)
= 30°20' + 40°35'
m(CXA) = 70°55'

Answer 2

The length of the ∠CXA is 70° 55'

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'
