Answer:
x=52
Step-by-step explanation:
One of the properties of parallelograms is that angle A = Angle C
5y-54 = 3x eq1
Another property of parallelograms is that angle A + angle B = 180 degrees
5y-54+2y-60 = 180
7y = 180+114 = 294
y = 42
Putting this value in eq1
3x = 5*42-54 = 210-54 = 156
x = 52
Answer:
12.5
Step-by-step explanation:
y varies inversely as x.
y = k/x
10 = k/20
200 = k
The constant proportion k is 200.
16 = 200/x
Cross multiply.
200 = 16x
200/16 = x
x = 12.5
