<u>Answer:</u>
<u>Step-by-step explanation:</u>
<u>We know that:</u>
- x = y
- 2(70 + 60) + x + y = 360
<u>Work:</u>
- 2(130) + x + x = 360
- => 260 + 2x = 360
- => 2x = 360 - 260
- => 2x = 100
- => x = 50
Hence, <u>the value of x is 50°.</u>

Answer:
To convert a fraction to a percent we take the fraction and multiply it by 100
If we want to convert 1/2 to a percent:

Or we can convert the fraction to a decimal and then multiply it by 100:
1/2 = 0.5 = 0.5 × 100 = 50%
