Based on a poll 63% of Internet users are more careful about personal information when using a public Wi-Fi hotspot What is the probability that
among three randomly selected Internet users, at least one is more careful about personal information when using a public Wi-Fi hotspot? How is the
result affected by the additional information that the survey subjects volunteered to respond?
The probability that at least one of them is careful about personal information is

step-by-step explanation:

a - base

b - exponent

so,

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.
