Question

BRAINIEST FOR THE CORRECT ANSWER!!

Answer 1

Answer:

A=7×5=35

B=18×5=90

C=11×5=55

Answer 2

Step-by-step explanation:

here

let the common ratio be x here

then a=7x

b=18x

c=11x

now in a triangle the sum of all angles is 180 degrees

so 7x +18x+ 11x =180°

also since a is the smallest angle

so a =35

here

7x =35

x=35/7

=5

so b =18×5=90°

c= 11×5= 55°
