Answer:
1. a + b + c = 180
2. b + d = 180
3. d = a + c
Step-by-step explanation:
1. a + b + c = 180:
Angles in a triangle add up to 180
2. b + d = 180:
Angles in a straight line equal 180 because they are supplementary angles
3. d = a + c:
ΔACD is an exterior angle, and ΔACB is interior adjacent, hence ∠a and ∠c add up to ∠d
It depend on what question an algebric can have as many but depends???
Only 1 and 51 are factors of 51.
Each pair of numbers gives a value then another value that is 1/2 of the first. So the answer would be
6 = 3
