The formula of a distance between two points:

$A(x_A;\ y_A);\ B(x_B;\ y_B)\\\\AB=\sqrt{(x_B-x_A)^2+(y_B-y_A)^2}$

$(7,\ 2);\ (8,\ -3)\\\\d=\sqrt{(8-7)^2+(-3-2)^2}=\sqrt{1^2+(-5)^2}=\sqrt{1+25}=\sqrt{26}$

$(0,\ 5);\ (-7,\ 0)\\\\d=\sqrt{(-7-0)^2+(0-5)^2}=\sqrt{(-7)^2+(-5)^2}=\sqrt{49+25}=\sqrt{74}$

Hello!

The Type I error means to reject the null hypothesis when the hypothesis is true. The probability asociated to this decision is the significance level of the test, symbolized α. For this problem, the probability of commiting a type I error (this means, rejecting the null hypothesis "the proportion of damaged light bulbs is less than 0.06" when the hypothesis is true) is 0.05.

I hope you have a SUPER day!
