Suppose that m∠a = m∠d. which other fact would guarantee that the triangles are similar?

The answer is either m∠B = m∠E  or  m∠C = m∠F.

Step-by-step explanation:  We are given two triangles, ΔABC and ΔDEF with m∠A = m∠D. We are to find the other fact that will guarantee that the two triangles are similar.

We know that the two triangles are similar if all the three angles of one triangle are equal in measurement to the corresponding three angles of the second triangle.

Also, if two angles of one triangle are congruent to the two corresponding angles of the other triangle, then the third pair of angles must also be congruent.

Therefore, if we have m∠B = m∠E  or  m∠C = m∠F, then we can conclude that the two triangles are similar.

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%
