Answer:
200 is the answer
Step-by-step explanation:
keep in mind 3*2=6
So 30% is 0.3
0.3*200=60
The respective missing proofs are; Alternate interior; Transitive property; Converse alternate interior angles theore
<h3>How to complete two column proof?</h3>
We are given that;
∠T ≅ ∠V and ST || UV
From images seen online, the first missing proof is Alternate Interior angles because they are formed when a transversal intersects two coplanar lines.
The second missing proof is Transitive property because angles are congruent to the same angle.
The last missing proof is Converse alternate interior angles theorem
because two lines are intersected by a transversal forming congruent alternate interior angles, then the lines are parallel.

Hope this helps ^-^
I can’t understand why everyone complicates this question. It can be easily solved by similar triangles.
In this png, we have something to make sure.

This also means AD=BD

This is our basic construction of D, which is going to help us.
∠ADC=∠DAB+∠B=2∠B=∠CAB

Actually these conditions suffice. Because I am just proving that △ACD∼△BCA
