In the figure, a : b:c=4:3:5. If AOB is a straight line, then the values of a ,b,c
respectively are
a. 75°, 45°, 60°
b. 48°, 36°, 60°
c. 45.759.60
d. 60°, 45°, 75°​

Answer 1

Answer:

$the \: answer \: will \: be$

a+b+c=180

4x+3x+5x=180

12x=180

x=15

a=4x=4(15)=60

b=3(x)=3(15)=45

c=5x=5(15)=75 degree OK friend this is urs answer

Answer 2

══════ •『 ♡ 』• ══════

4x +3x +5x = 180(angles in same side)

12x = 180. degree

x. = 180 /12

x = 15

4 x = 15 ×4

=. 60

3x = 15 ×3

45

5x= 5 ×15

=75
