4 Mr. Serat is choosing tiles for a client's kitchen. Identify three pairs of similar triangles. Explain.
А
AABC where m2A = 24 and mZB = 96
B
ADEF where mZD = 24 and mZE = 64
с
AGHI where m2 = 24 and m/1 = 92
D
AJKL where m2 = 24 and mZL = 99
E
AMNO where m/M = 24 and mzo = 60
F
APQR where mZP = 24 and m20 = 57

Pairs:

ABC:MNO

DEF:GHI

JKL:PQR

Step-by-step explanation:

To solve this you must find the missing angle. Similar triangles have the same angles.

ABC

180 - 96 - 24 = 60

Angles: 96-24-60

DEF

180 - 24 -64= 92

Angles: 24-64-92

GHI

180-24-92 = 64

Angles: 24 - 92- 64

JKL

180 - 24 - 99 = 57

Angles: 24 - 99 - 57

MNO

180 - 24 - 60 = 92

Angles: 24-60-92

PQR

180 - 24 - 57 = 99

Angles: 24 - 57 - 99

Match the triangles with the same angles and those are the similar triangles.

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1
