Answer:
∠A = 70°
Step-by-step explanation:
I'm... guessing this is what you mean? It would've been helpful if you'd provided pictures.
Since all parallelograms consist of two pairs of vertically opposite angles, ∠A and ∠C are equivalent.
Which means that 2x + 50 = 3x + 40.
In which you solve the equation.
2x + 50 = 3x + 40
-2x -2x
50 = x + 40
-40 -40
x = 10
Now, to find ∠A, substitute x into the equation:
∠A = 2x + 50
x = 10
∠A = 20 + 50
∠A = 70
Hence, ∠A = 70°
Answer -3(2m-3n+4)

Given



Required
Chances that you missed the appointment
First, calculate the number of minutes of the radio station



Convert to seconds

Since you turn on at 8:18:00, then you've missed the broadcast from the start till 8:18:00
So, we have:


Convert to seconds

The probability that you missed is:
