The original cost of her dinner was 20 dollars.
First set up an equation,
.30x = 6
(x represents the original cost)
To isolate x, divide both sides by .30.
x = .30/6
x= 20 (the original cost)

Can someone help me on this math problem.?
Tju [1.3M]

All sides of a rhombus are equal.

So the triangle containing the marked angle 124 degrees is isosceles and the base angles x and z are equal.

So, because there are 180 degrees in a triangle.

x + z + 124 = 180

z + z + 124 = 180   ( because  m < x = m < z)

2z = 180 -124 = 56

z = 56/2  = 28 degrees   (answer).
