The main area formula is A= 5x s x r/ 2
where s is a side
r is the radius, r can be found as following
r is the hypothenuse, so tanα=a/S, where S=s/2=7
tanα=22/7=Pi, so <span>α=arctanPi= 72.3°
</span>for finding r, r = a/sin <span>α=22/sin 72.3°=23
</span>so finally
the area is A= (5x 14x 23 )/2=808
The answer is a,b, and c. 1,3,9
Answer:
If two pairs of corresponding angles in a pair of triangles are congruent, then the triangles are similar. We know this because if two angle pairs are the same, then the third pair must also be equal. When the three angle pairs are all equal, the three pairs of sides must also be in proportion.
