In the diagram the measure of angle 3 is 105 degrees which angle must also measure 105? A.1 B.4 C.6 D.8 I NEED HELP ASAP PLZZZZ!!!!!!!!!

Answer: The correct option is (A). angle 1.
Step-by-step explanation: In the given diagram, the measure of ∠3 is 105°.
We are to find the angle that must also measure 120°.
We know that the measures of two vertically opposite angles are equal.
In the given diagram, since ∠1 and ∠3 are vertically opposite angles.
So, the measures of ∠1 and ∠3 are equal.
That is,
m∠1 = m∠3.
Also, m∠3 = 105°.
Therefore, m∠1 = 105°.
Thus, the measure of angle 1 must be 105°.
Option (A) is correct.
Answer:
(A) 1
Step-by-step explanation:
From the given diagram, we have The measure of the [tex]{\angle}3[/tex] is [tex]105^{\circ}[/tex].
Now, using the property of straight lines, we have
[tex]m{\angle}3=m{\angle}1=105^{\circ}[/tex] (Because they are vertically opposite angles).
Hence, only the [tex]{\angle}1[/tex] has the same measure as [tex]105^{\circ}[/tex].
Therefore, option A is correct.
