Answer:
1/2 is the correct answer,
Algebraic expressions are combinations of variables , numbers, and at least one arithmetic operation. For example, 2x+4y−9 is an algebraic expression. Term: Each expression is made up of terms. A term can be a signed number, a variable, or a constant multiplied by a variable or variables.

Answer:
∠1=54°
∠2=54°
∠3 = 126°
Step-by-step explanation:
We need to find ∠1, 2 and 3
Since a traversal cut parallel lines we would use supplementary angles , congruent angles rules to solve the problem.
Angle 1 and 126 are supplementary angles.
They add up to make 180
So, ∠1 + 126 = 180
∠1 = 180-126
∠1 =54
We get ∠1=54°
Now, ∠1 ≅ ∠2, because they are corresponding angles and if traversal cut parallel lines, corresponding angles are congruent.
So ∠1 ≅ ∠2 therefore, ∠2=54°
Now, for finding measure for ∠3, we know that 126 and ∠4 are corresponding angles and corresponding angles are congruent.
So, ∠4 = 126°
We know that ∠3 and ∠4 are vertical angles.
And if traversal cut parallel lines, vertical angles angles are congruent.
So, ∠3 = 126°
