3(x+5)=39
3 * x + 3 * 5 = 39
3x + 15 = 39
3x = 39 - 15
3x= 24
x = 8

Answer:
w = 34°
Step-by-step explanation:
Every quadrilateral is equal to 360 degrees. If you know 3 out of the 4 angles, then what you need to do is add up each angle and subtract the sum from 360 to find the remaining angle.
90 + 90 + 146 = 326
360 - 326 = 34
w = 34
