Q8. The angles of a triangle
are in the ratio 3: 1:2. What is
the measure of the largest
angle?​

Answer 1

Answer:

3x+x+2x=180

Step-by-step explanation:

6x=180

x=180/6=30

30*3=90

1*30=30

30*2=60

longest side=1st side

Answer 2

Answer:

kindly see the answer below...

Step-by-step explanation:

Here,

The angles of a triangle

The angles of a triangle are in the ratio 3: 1:2. .....

therefore,

$the \: sum \: ofthe \: angles \: of \: a \: triangle \: is \: 180$

$so \: let \: the \: angles \: be \: \\ 3x \\ x \\ and \: \: 2x$

then,

$3x + x + 2x = 180$

$or \: 6x = 180$

$or \: x = 30$

so,

$the \: angles \: are \\ 3x = 3 \times 30 = 90 \\ x = 1 \times 30 = 30 \\ 2x = 2 \times 30 = 60$

Now, the measure of the largest angle is

$90 \: degree$

I think this is the required answer...

thanks a lot...
