What’s the answer for it pl he me

Remember that angles across from each either are equal. I say across from each other but I know that’s hard to understand look at the image I attached, I am referring to yellow angle. See how the yellow angle and the two w’s form a straight line, it’s draw in red in my image. A straight line is 180. So 76+2w=180 Solve it by isolating the variable w. Subtract 76 from both sides. 2w=104 divide both sides by 2. w=52
