3. Two students to prove whether or not ⊿ ~⊿. Malcolm used the SAS similarity postulate to show that the triangles are similar because

= ∠≅∠.

Tasha used the triangle angle sum theorem and the AA postulate to show that the triangles were similar because∠ ≅ ∠ ∠ ≅ ∠.

Who is correct?

a. Malcolm only

b. Tasha only

c. both Malcolm and Tasha

d. neither Malcolm nor Tasha

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

3

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3
