36= 12.5% because 25%+62.5%= 87.5%
So 100%-87.5%=12.5%
87.5%-12.5%= 75%
36+36=72=25%
72+72+72+72= 288 = 100%
So the total number of pages in the magazine is 288

Answer:
140
Step-by-step explanation:
<u>As per picture:</u>
∠PTQ and ∠RTS are vertical angles and they are equal
- ∠PTQ = (x + 28)°
- ∠RTS = (2x + 16)°
- ∠PTQ = ∠RTS
- x + 28 = 2x + 16
- 2x - x = 28 - 16
- x = 12
∠PTR is supplementary with ∠PTQ and their sum is 180°
- ∠PTQ = 12 + 28 = 40°
- ∠PTR = 180 - 40 = 140°
Answer:
w = 25
Step-by-step explanation:
- 45+30 = 100 - w
- 75 = 100 - w
- w = 100 - 75
- w = 25
