Answer:
The answer is 55.
Step-by-step explanation:
1. angle ADB and BDC = 180.
180-80= 100 (angle BDC is 100)
because a triangle is 180 degrees, you can figure out CBD...
2. BDC + DCB is the same as
100+25=125
3. 180-125=55
Answer:
c
Step-by-step explanation:
If the dot product of the vectors is zero then they are perpendicular
(5, - 1) • (- 3, 6)
= (5 × - 3) + (- 1 × 6) = - 15 + (- 6) = - 15 - 6 = - 21 ≠ 0
Since product is not zero vectors are not perpendicular
