Triangle ABC is an isosceles triangle.
Solution:
Given data:
∠ABC = 70° and ∠ACD = 55°
<em>If two parallel lines are cut by a transversal, then alternate interior angles are congruent.</em>
m∠BAC = m∠ACD
m∠BAC = 55°
<em>Sum of the angles in a straight line add up to 180°.</em>
m∠ACD + m∠ACB + m∠ABC = 180°
55° + m∠ACB + 70° = 180°
m∠ACB + 125° = 180°
Subtract 125° from both sides, we get
m∠ACB = 55°
In triangle ABC,
∠BAC = 55° and ∠ACB = 55°
∠BAC = ∠ACB
Two angles in the triangle are equal.
Therefor triangle ABC is an isosceles triangle.

Answer:
<u>The correct answer is B. 3/10.</u>
Step-by-step explanation:
1. Let's calculate the probability of spinning an odd number:
We can spin an odd number (1, 3 or 5) out of 5 events, it means that the probability of spinning an odd number is:
3/5
2. Let's calculate the probability of getting tails on the coin:
We can toss a coin and get tails one out of 2 events, it means that the probability of getting tails on the coin is:
1/2
3. These are independent events because the fact that we spin an odd number does not affect the probability of getting tails on the coin, thus:
Probability of spinning an odd number and getting tails on the coin =
3/5 * 1/2 = 3/10
<u>The correct answer is B. 3/10</u>
