Given that bisects ∠cea, which statements must be true? select three options.
m∠cea = 90°
m∠cef = m∠cea + m∠bef
m∠ceb = 2(m∠cea
∠cef is a straight angle.
∠aef is a right angle.

m∠CEA = 90°

∠CEF is a straight angle

∠AEF is a right angle

Step-by-step explanation:

we know that

BE bisects ∠CEA > given problem

so

m∠CEB=m∠BEA

m∠CEA=m∠CEB+m∠BEA

The measure of angle CEA is a right angle > m∠CEA=90°

The measure of angle CEF is a straight angle > m∠CEF=180°

m∠CEF=m∠CEA+m∠AEF

The measure of angle AEF is a right angle > m∠AEF=90°

therefore

The statements that must be true are

m∠CEA = 90°

∠CEF is a straight angle.

∠AEF is a right angle

answer: y=0 if that is what u r looking for
