Question

please tell me correct answer​

Answer 1

Answer:

d) 60,45,75

Step-by-step explanation:

given: a:b:c=4:3:5

so, let a,b and c be 4x,3x and 5x respectively.

a+b+c = 180 (AOB is a straight line)

4x+3x+5x = 180

12x = 180

x = 15

a = 4x = 60

b = 3x= 45

c = 5x = 75

Answer 2

Let the angles be 4x , 3x & 5x

${\sf\bold{These~form~a~linear~pair~}}$

${\sf\bold{4x~+~3x~+~5x~=~180°}}$

${\sf\bold{12x~=~180°}}$

${\sf\bold{x~=~15}}$

$\large{\sf{.°.~angles~are~60°,~45°,~75°}}$
