Answer:
Step-by-step explanation:
External angle equals to the sum of opposite internal angles
z - 41° + z - 20° = z + 40°
2z - 61° = z + 40°
2z - z - 61° = 40°
z - 61° = 40
z = 40° + 61°
z = 101°
First you would need to Simplify <span>{3}^{2}<span>3<span>2</span></span></span> to <span>99
Next you would need to : </span>Use Negative Power Rule =9÷31
<span>
then you would need to use a ÷ b/c = a * c/b and get 9*3
And you will lastly get 27</span>
