If two line crosses, then the vertical angles are the angles opposite each other. In this way, these angles share the same vertex. So, the vertical angles are always equal. Therefore, in this problem, the right answers are:
1. ABE and CBD
Notice that the vertex is B, so these two angles share the same vertex. Accordingly, these two angles are vertical angles.
2. ABC and EBD
The same reasoning is applied here. The vertex is also B. Notice that <em>the angles CBD and ABD add up to 180 degrees. </em>
2(x-5) = 9
2x - 10 = 9
2x = 19
x = 9.5
232 bc 15500 divided by 100 is 155 then 155 times 232 is 32860
Answer:
area of trapezium =1/2(a+b)*h
=1/2(7+10.4)*6.7
=1/2(17.4)*6.7
=1/2(116.58)
=116.58/2
=58.29 square cm
