Answer:
answers below hope you found it
Step-by-step explanation:
a.
3x+5x+7x+9x=360degree(quadilateral)
24x=360degree
x=360/24
x=15
therefore the angles are,
3x=3 x 15=45
5x=5 x 15=75
7x=7 x 15=105
9x=9 x 15=135
b.
2x+2x+3x+5x=360degree(quadilateral)
12x=360
x=360/12
x=30
therefore the angles are,
2x=2 x 30=60
2x=2 x 30=60
3x=3 x 30=90
5x=5 x 30=150
