Answer: AA similarity theorem.
Step-by-step explanation:
Given : AB ∥ DE
Prove: ΔACB ≈ ΔDCE
We are given AB ∥ DE. Because the lines are parallel and segment CB crosses both lines, we can consider segment CB a transversal of the parallel lines. Angles CED and CBA are corresponding angles of transversal CB and are therefore congruent, so ∠CED ≅ ∠CBA.
Also ∠C ≅ ∠C using the reflexive property.
Therefore by AA similarity theorem , ΔACB ≈ ΔDCE
- AA similarity theorem says that if in two triangles the two pairs of corresponding angles are congruent then the triangles are similar .
Answer:
Probability that A wins is 2/3.
Step-by-step explanation:
player A can win in 2 ways
1) Player A wins immediately by getting head
2) Player A loses immediately by getting tail but wins ultimately as player B gets losses.
a) Probability of 1 to happen is 1/2.
b) Similarly for the event 2 to happen the condition is that A get's a tail and B losses.
Let probability that A wins is 'p' thus we have
Solving for 'p' we get
p= 2/3.
