Which cannot be the angle measurements of triangle ABC? OmZA = 55°, mZB = 65°, mZC = 60° OmZA = 60°, mZB = 60°, mC = 60°
MZA= 57°, MZB = 58°, mZC = 65°
MZA = 61°, mZB = 57°, mZC = 61°

Last option is the correct answer.

Step-by-step explanation:

Since, 61° + 57° + 61° = 179° < 180°

Therefore,

cannot be the measurements of triangle ABC.

add an image !

step-by-step explanation:

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
