Answer 1

5x + 4x + 6x = 180
15x = 180
x = 360/15 = 12
X = 5x = 60
Y = 4x = 48
Z = 6x = 72

Answer 2

Hello friend....☺

Here is your solution________________

♦ Let the ratios be "x".
=> x° = 5x
=> y° = 4x
=> z° = 6x

According to question,

=> 5x + 4x + 6x = 180° { sum of all angles of a line is 180°}

=> 15x = 180°
=> x = 180°÷ 15
=> x = 12

Now , x° = 5x
=> x° = 5 × 12 = 60°
=> y° = 4x
=> y° = 4× 12
=> 48°
Also, z° = 6x
=> z° = 6 × 12
=> 72°

Thanks...☺
