Question

plzzz do this fast I can't do it plzzźzz help me​

Answer 1

Answer:

2 /_ A = 3 /_ B = 6 /_ C  

Let 2 /_ A = 3 /_ B = 6 /_ C = X° .

Then,  

/_ A = (X/2)° , /_B = (X/3)° and /_ C = (X/6)°

Therefore,  

X/2 + X/3 + X/6 = 180

as all angle of a triangle sum up to 180

3X + 2X + X = 1080  ( 180 x 6) ..... as 6 is the LCM

6X = 1080

X = 180  

Therefore,

/_ A = X/2 = 180°/2 = 90°  

/_ B = X/3 = 180°/3 = 60°  

And,  

/_ C = X/6 = 180°/6 = 30°.

Answer 2

Answer:

For doing these types of ques

u have to take a constant

2<A =K

3<B =K

6<C= K

hence

<A = K/2

<B = K/3

<C = K/6

So according to angle sum property of triangle

<A +<B +<C = 180°

K/2 + K/3 + K/6 = 180°

(3K + 2K + K )/6 = 180°

6K = 180 × 6

Hence

K = 180°

Hence

<A= 90° (K/2)

<B = 60° ( K/3)

<C = 30 ° (K/6)

Hence measure of smallest angle 30°
