Answer:

I. Evaluate the largest angle when x = 15

Explanation:

First, solve for x:

x + 8x + x + 30 = 180

10x = 180 - 30

10x = 150

x = 15

Here in the question, his friend wants to find the largest angle in triangle.

So, input x = 15 in the largest angle.

Which is, 8x = 8(15) = 120° <--- largest angle in the triangle.

Answer:

a) min: 0; max: 21

b) min: 34; max: 55

Step-by-step explanation:

In the attached Venn diagrams (part c), the overlap of the two circles represents the number on both teams.

a) In the top diagram, there is no overlap, so the number on both teams is 0.

In the bottom diagram, there is complete overlap between the teams, so the maximum number that play both sports is 21 (the minimum team size of the two teams).

both teams minimum: 0; maximum: 21

b) The number on neither team is the number outside both circles. The minimum number will correspond to the case where there is no overlap between teams. In that case, there are 66 team players, so 34 people who are on neither team.

The maximum case is that where the teams completely overlap, so the number not on either team will be those not on the football team: 55 people.

neither team minimum: 34; maximum: 55
