Question

In a triangle if 4LA =3LB=12LC, find the angles. ​

Answer 1

Answer:

<A=67.5

<B=90

<C=22.5

Step-by-step explanation:

• given 4<A=3<B=12<C
• lets consider x= 4<A=3<B=12<C
• so x= 4<A <A= x/4 (i)
• x=3<B <B=x/3 (ii)
• x=12<C <C= x/12 (iii)
• By angle sum property <A+<B+<C=180°
• putting values into eq- x/4+x/3+x/12=180°
• (3x+4x+x) /12=180°
• 8x= 180×12=2160
• x=2160/8=270
• So putting x=270 in eq i ,ii,and iii
• <A=270/4= 67.5
• <B=270/3=90
• <C=270/12=22.5 ans.
