The perimeter of an isosceles triangle is given by the formula p = 2a + b, where a is the length of each of the equal sides and b is the length of the third side. A) re-arrange the formula to isolate for “b”.

B) re-arrange the formula to isolate for “a”.

C) an isosceles triangle as a perimeter of 43 cm. The length of the two equal sides is unknown, but the third side length is 18 cm. What is the length of each of the equal sides?

This is urgent, can someone please show the steps on how to find the answer.

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down

i ran through it by the other answer is wrong
