(if the last five is an exponent, here is the answer)
5 • 10^5
first work on the exponent
5 • 100,000
multiply
500,000
If that number is x:
120 = 1.60x
x = 120/1.60=75
Opposite angles of parallelogram are equal.
sum of interior angles of parallelogram is 360 degrees.
Therefore,
A + B + C + D = 360
x + 145 + x + 145 = 360
x = 35
Therefore angle C is 35 degrees
