Answer:
55,050
Step-by-step explanation:
The slop is 3 I hope that helped?
Multiply 4x2 since the opposite side is the same length, and then subtract the answer (8) from the perimeter (14 units) and you’ll get 6. and then divide 6 into 2 since there is 2 more congruent sides, and you will get 3.
Answer:
21°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
subtract the sum of the 2 given angles from 180 for the other angle
other angle = 180° - (90 + 69)° = 180° - 159° = 21°
Answer:
SAS postulate , since an angles is equal in both triangles plus the diagonals are divided equally means that's equal in both of the triangles
