Help Please! Thank you have a nice day! :)
Triangle TAB has a perimeter of 40 cm. Could the measures of the sides, as shown, actually represent the measures of the sides of a triangle? Justify your answer.

Answer 1

Answer:

AT=20cm, BT=12cm, AB=8cm

Step-by-step explanation:

B.T.P-

AT+BT+AB=40

4x+(2x+2)+x+3=40

7x+5=40

7x=40-5

7x=35

x=35/7

x=5

Therefore AT=4×5=20

BT=2×5+2=12

AB=5+3=8
