Answer from: DrDre02

The pair of triangles that are congruent by ASA is $\boxed{\bf option (d)}$ .

Further explanation:

Triangles are congruent when all the corresponding sides and interior angles are equal.

There are four theorems by which we say that the triangles are congruent.

1.Side-Side-Side(SSS)

If all the three sides of a triangle are equal to the corresponding sides of the other triangle, then the two triangles are congruent by SSS theorem.

2.Angle-Side-Angle(ASA)

If any two angles and the included side between the angles of one triangle are equal to the corresponding two angles and the included side between the angles of the second triangle then the two triangles are congruent by ASA theorem.

3.Side-Angle-Side(SAS)

If any two sides and angle between the sides of one triangle are equal to the corresponding two sides and angle between the sides of the second triangle then the two triangles are congruent by SAS theorem.

4.Hypotenuse Leg (HL)

If the hypotenuse and side of a right angled triangle is equal to the hypotenuse and a side of the other right angled triangle then the triangles are congruent by HL theorem.

Option (a)

The first figure shows one side is included between the two angles but the second figure shows two angles and one side as shown in below attachment.

Both the figures don’t have a single property from the above mentioned properties.

Therefore, option (a) is incorrect.

Option (b)

The first figure shows one angle between the two sides and the second figure also shows one angle between the two sides as shown in below attachment.

Both have the same property.

Therefore, the triangles are congruent by SAS rule not by ASA.

Thus, option (b) is incorrect.

Option (c)

The first figure shows one angle between the two sides and the second figure also shows one angle between the two sides as shown in below attachment.

Both have the same property.

Therefore, the triangles are congruent by SAS rule not by ASA rule.

Thus, option (c) is incorrect.

Option (d)

The first figure shows two angles and one side is included between them and the second figure shows two angles and one side is included between them as shown in below attachment.

Both have the same property.

Therefore, the triangles are congruent by ASA rule.

Thus, option (d) is correct.

Hence, the $\boxed{\bf option (d)}$ is correct as the triangles are congruent by ASA rule.

Amachine that produces a special type of transistor (a component of computers) has a 2% defective rate. the production is considered a random process where each transistor is independent of the others. (a) what is the probability that the 10th transistor produced is the first with a defect? (b) what is the probability that the machine produces no defective transistors in a batch of 100? (c) on average, how many transistors would you expect to be produced before the first with a defect? what is the standard deviation? (d) another machine that also produces transistors has a 5% defective rate where each transistor is produced independent of the others. on average how many transistors would you expect to be produced with this machine before the first with a defect? what is the standard deviation? (e) based on your answers to parts (c) and (d), how does increasing the probability of an event aâ†µect the mean and standard deviation of the wait time until success?
