Answer 1

Step-by-step explanation:

The angles add upto 360 degrees. Which implies that

${(x - 10)}^{0} + {x }^{0} + {(2x)}^{0} + {(x - 30)}^{0} = {360}^{0}$

Simplifying, we get

${(5x - 40)}^{0} = {360}^{0} \\ {(5x)}^{0} = {360}^{0} + {40}^{0} \\ x = 400 \div 5 \\ x = {80}^{0}$

Hope this helps ;)
