Question

Given the following diagram, enter the required information. m BXA = 30° 20', m CXB = 40° 35'. m CXA __° __'.

Answer 1

I saw the diagram.

m∠BXA = 30° 20'
m∠CXB = 40° 35'

m∠CXA = ?

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

Answer 2

the picture in the attached figure

we know that

m∠BXA =
`30`°
`20`'
m∠CXB =
`40`°
`35`'

m∠CXA = ?

m∠CXA = m∠BXA + m∠CXB
m∠CXA =
`30`°
`20`' +
`40`°
`35`'
m∠CXA =
`70`°
`55`'

therefore

the answer is
m∠CXA =
`70`°
`55`'
