Answer:

AB = 16

Step-by-step explanation:

The perimeter is the sum of all 5 sides of the pentagon

Sum the 5 sides, equate to 69 and solve for x

12 + 3x + 10 + x + 3 + 2x + 2 = 69

6x + 27 = 69 ( subtract 27 from both sides )

6x = 42 ( divide both sides by 6 )

x = 7

AB = 2x + 2 = (2 × 7) + 2 = 14 + 2 = 16

The measure of the exterior angle of the triangle is what degree?

RSB [31]

Answer:

92°

Step-by-step explanation:

By exterior angle theorem:

$(2x - 2) \degree = x \degree + 45 \degree \\ \\ (2x - 2 - x) \degree = 45 \degree \\ \\ (x - 2) \degree = 45 \degree \\ \\ (x - 2) = 45 \\ \\ x = 45 + 2 \\ \\ x = 47 \\ \\ (2x - 2) \degree = (2 \times 47 - 2)\degree \\ \\ (2x - 2) \degree = (94 - 2)\degree \\ \\ (2x - 2) \degree = 92\degree \\ \\ measure \: of \: the \: exterior \: angle \\ = 92 \degree$

A. 42 tickets

Explanation

Since everyone must go on the ride together the number of tickets must be a multiple of 8 (since there are 8 people). 42 is the only number that is not a multiple of 8.
