Answer:
it would be 140 . 40+3+140=180
Step-by-step explanation:
<em>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.</em>
Answer:
D. 98 ft.^2
Step-by-step explanation:
A= b*h
=13*8
=104 ft.^2
Because there is a piece missing, we know it must be under 104 ft.^2. They didn't give us enough information to find the complete area of the missing triangle, so I used the process of elimination. With the responses given and this information, we can assume that the answer is 98 ft.^2.
