Answer:
- See below
Step-by-step explanation:
<h3>#10</h3>According to diagram we have
- TU ║ WV and TV is transversal
- ∠T ≅ ∠V as alternate interior angles
- TX ≅ VX
- ∠TXU ≅ ∠WXV as vertical angles
Conclusion
- ΔTXU ≅ ΔWXV by ASA (angle-side-angle)
ABC and DCB are right triangles but corresponding sides have different ratio
- 5/5 ≠ 13/12
So triangles are not similar
<h3>#12</h3>According to Pythagorean the missing hypotenuse is
The triangles have three congruent pairs of sides (3, 4 and 5 units) so are congruent by SSS (or HL)

Answer:
Step-by-step explanation:
Straight line is an angle whose vertex point(O) has a value of 180. The arms (OA & OB) of the straight line angle lies opposite to each other from the vertex point
Sum of all the angles in a straight line = 180
From this you can find the value of unknown angle, if other angles are given.
∠AOC + ∠BOC = 180
