Answer 1

Answer:

Given, In triangle abc,

20angleA = 12angleB = 15angleC

Next step i don't know

So sorry, bro

Sorry!!!!!

Answer 2

Step-by-step explanation:

Statement is given as 20 angle A = 12 angle B = 15 angle C

angle A + angle B + angle C = 180° (angle sum property)

here angle A = ( 12 / 29 ) angle B

12 angle B = 15 angle C

angle B = ( 15 / 20 ) angle C

angle A = ( 12 / 20 ) × ( 15 / 12 ) angle C

therefore, angle A = ( 3 / 4 ) angle C

( 3/4 ) angle C + ( 15/20 ) angle C + angle C = 180°

[ 3/4 + 15/ 12 + 1 ] angle C = 180°

[ ( 3×3 / 4×3 ) + ( 15 / 12 ) + ( 12 / 12 ) ] angle C = 180°

( 36 / 12 ) angle C = 180°

3 angle C = 180°

angle C = 180° / 3

angle C = 60°

then for angle A and angle B,we have to find for 1

therefore ( 60 / 12 ) = 4

angle A = 4 × 20

= 80°

angle B = 4 × 12

= 48°

angle C = 60° ( which we get above)
