Cos60 degrees=1/2, so AK/AB=1/2. Since AK=KD, AK=1/2AD=1/2AB. Therefore, AB=AD. This is a rhombus, with four equal sides. Triangle ABK is congruent to triangle DBK (SAS), since AK=KD, angle AKB=angle BKD=90, and BK=BK. Therefore, BD=AB. The sum of four side lengths is 24. Each side length is equal to 24/4=6. BD=6.
Answer:
x = 271 degrees
Step-by-step explanation:
The difference is the subtraction between the numbers;
15-5y
Factor out 5 because it's a common factor;
5(3-y)
Answer:
Becky Did the Proof Wrong, since a Postulate is two adjacent angles that can be added to t=find the measure of another angle,
AKG + GKB= 180 Degrees Is the definition of Supplementary angles, since a supplementary angle is the sum of two angles equaling 180 Degrees
Otherwise, they follow the same steps in Steps 1,3, and 4
Step-by-step explanation:
