Step-by-step explanation:
are vertically opposite angles.

Answer:
14 cm
Step-by-step explanation:
There are 2 equal sides of 13 cm, thus the third side is
third side = perimeter - 13 - 13 = 50 - 26 = 14
Answer:
Below.
Step-by-step explanation:
These reasons will probably be similar to the US conventions but not exactly the same ( I'm using the UK conventions).
1. Given
2. Given.
3, Opposite sides of a parallelogram.
4. Opposite sides of a parallelogram.
5. This side is common to both triangles.
6. The triangles are congruent by 3 equal sides ( I think that is SSS).
When you GRAPH an equation or inequality you plot all of the points that satisfy it.
Answer:
12
Step-by-step explanation:
Put in 3 for x and 3 for y:
3(3 + 3 - 2)
3(4)
12
