The diagram shows a length and angle measure in a scale drawing of a triangular roof truss. In the actual roof truss, the length of the side corresponding to AB is 35 feet, the length of the side corresponding to BC is 20 feet, and their included angle measures 109°. For what length AB is the scale drawing correct?

the answer is c.

for continuous functions, they continue in the same pattern and you have to find that pattern kinda like slope

96 39 cause 135 -96=39 im smart (i used a calculater)

the answer to this is a. a^2 + b^2 = c^2

hello,

elba writes the following proof for the theorem: if the diagonals of a quadrilateral bisect each other, the quadrilateral is a parallelogram:

elba's proof

1. for triangles aob and cod, angle 1 is equal to angle 2 as they are vertical angles.

2. ao = oc and bo = od because it is given that diagonals bisect each other.

3. therefore, the triangles aob and cod are congruent by sas postulate.

4. similarly, triangles aod and cob are congruent.

5. by cpctc, angle abd is equal to angle cdb and angle adb is equal to angle cbd.

6. as the are congruent, the opposite sides of quadrilateral abcd are parallel.

7. therefore, abcd is a parallelogram.

which is the missing phrase in elba's proof?

answer - opposite
