Question

The angle of a triangle are in the ratio 3: 5: 7 Find the measure of these angles​

Answer 1

Answer:

Step-by-stepLet the common ratio be x

So the angles become 3x 5x and7x

Now we know that 3x+5x+7x=180°{anglesum properly of triangle}

So 15x=180°

x=180÷15

=12

Thus first angle is 36°

second angle is 60°

And third angle is 84°

Hope it helps

Answer 2

Let the common ratio be x

Thus first angle is 36°

second angle is 60°

And third angle is 84°
