Answer:
Bottom Right: Following CPCTC (Corresponding Parts of Congruent Triangles are Congruent), we can see that the corresponding parts are congruent (for example, UV ≅ XY, ∠W ≅ ∠T, etc.)
Bottom left: Again, CPCTC.
DE ≅ QP
∠E ≅ ∠Q
etc.
Not B), because, while BC ≅ GH, the angles are not all the same, which makes it non-congruent.
Not A), because while they both have right angles, the sides are not congruent (cannot be simplified to the same ratio).

Answer:
The measure of the third angle is a 90 degrees
Step-by-step explanation:
Let
A and B ----> two complementary angles in a triangle
C ---> the measure of the third angle in a triangle
we know that
If two angles are complementary, then their sum is equal to 90 degrees
so
---> equation A
Remember that
The sum of the interior angles in any triangle must be equal to 180 degrees
so
----> equation B
substitute equation A in equation B

solve for C
subtract 90 degrees both sides


therefore
we have a right triangle

Answer:
105
Step-by-step explanation:
By solving for the other triangles, we know that the angles of a triangle add up to be 180 degrees. The angle for the triangle on the left is 25 and for the triangle on the right is 50. So we have the measurements, 25, 50 and x for our middle triangle from which we can see x=105
