Answer 2

Step-by-step explanation:

$90 + 1 \frac{1}{2} x + 1 \frac{1}{2} x + \frac{5}{2} x + 3 \frac{1}{2} x = 360 \\ 90 + \frac{3}{2} x + \frac{3}{2} x + \frac{5}{2} x + \frac{7}{2} x = 360 \\ \frac{3}{2} x + \frac{3}{2} x + \frac{5}{2} x + \frac{7}{2} x = 360 - 90 \\ \frac{3x + 3x + 5x + 7x}{2} = 270 \\ \frac{18x}{2} = 270 \\ 9x = 270 \\ x = \frac{270}{9} \\ x = 30$

1st angle 90°

2nd angle = 3/2 × 30 = 45°

3rd angle = 3/2 × 30 = 45°

4th angle = 5/2 × 30 = 75°

5th angle = 7/2 × 30 = 105°
