a) 36°,60°,106°,158°
b) 36°,60°,108°,156°
c) 30°,60°,90°,180°
d) 30°,60°,100°,170°​

Answer 1

Answer:

option b) 36° ,. 60° ,108° , 156°

Step-by-step explanation:

÷12) 36 :60:108:156

3 : 5 : 9 : 13

Answer 2

Answer:

$3x + 5x + 9x + 13x = 360$

$30x = 360$

$x = 12$

$3x = 3(12) = 36 \: degree$

$5x = 5(12) = 60 \: degree$

$9x = 9 \times 12 = 108$

$13x = 13(12) = 158$
