An expression when dealing with math does not have an equal sign. So, technically 12m + 12n is already an expression.
It can be simplified to
12(m + n) if that helps any. Good luck!
Answer:
- ∠UTC = 55°
- ∠UCD = 70°
- ∠BCT = 55°
Step-by-step explanation:
In this figure of overlapping parallelograms, each angle is related to the others by several different theorems involving triangles, parallelograms, and parallel lines. That is, there are several different ways one can arrive at the answers to this question.
__
<h3>UTC</h3>
∠UTC ≅ ∠UDC = 180° -∠EDU . . . opposite angles of parallelogram; linear pair
∠UTC = 180° -125° = 55°
__
<h3>UCD</h3>
∠UCD ≅ ∠TBC = 180° -∠TBA . . . . corresponding angles; linear pair
∠UCD = 180° -110° = 70°
__
<h3>BCT</h3>
∠BCT ≅ ∠UTC = 55° . . . . alternate interior angles
