Answer:

a) x = 69°

b) y = 69°

Step-by-step explanation:

a. Given that AB and CD are parallel lines, therefore:

x = 69° (alternate interior angles are congruent to each other)

b. y + 111° = 180° (consecutive interior angles are supplementary)

y = 180° - 111° (substraction property of equality)

y = 69°

Is the following conditional true? If p<2, then p≤2.

Romashka-Z-Leto [24]

If this is the only information you are given then no. This is because the < sign means that p is less than 2. The second sign cannot be true if the first one is because the second sign says that p is less than or equal to 2.
