Logan is reading about architecture and learns that trusses can be used to support roofs. He wants to find the measures of the angles on a truss.The measure of ∠AFC is 120°, and the measure of ∠BFC is 95°. Which equation can you use to find the measure of ∠AFB?

Respuesta :

Answer:

Hence the measure for the ∠AFB is 25 degrees.

Step-by-step explanation:

Given:

A trusses supports the roof

(Refer the Attachment). For the angles made in it.

To Find:

Which equation can you use to find the measure of ∠AFB?

Solution:

The figure includes the 3 angles as follows,

∠AFB,∠AFC,∠BFC

∠AFC is bigger angle given so both the angle will be included in that

Because the ∠AFC  represent the outside layout angle for the roof trusses.

∠AFC =∠AFB+∠BFC

Hence putting all given values we get ,

∠AFB= ∠AFC -∠BFC

∠AFB =120-95

∠AFB= 25 degrees

Hence the measure for the ∠AFB is 25 degrees.
