9x=153
Step-by-step explanation:
540-139-71-92-9x-5x=0
238-14x=0
238=14x

Answer: Cal's answer must be incorrect because the sum of angles is incorrect.
Step-by-step explanation:
The sum of all interior angles of a triangle is 180 degrees.
According to Cal, the three angles of the triangle has magnitude 65, 45 and 60 respectively.
Sum of angles = 65+45+60
i.e. Sum of angles = 170 which is not equal to 180
Hence, Cal's answer must be incorrect because the sum of angles is incorrect.
The perimeter means you add up all the sides
so you do
(12b-8) + (12b-8) + (9b+8)
now you just add the like terms
12b+12b+9b = 33b
-8+-8+8= -8
so the perimeter is 33b-8
