Question

If the angles of a triangle are in the ratio1:4:5, find the angles ​

Answer 1

Step-by-step explanation:

Let the Angles be x, 4x & 5x

Now by Angle Sum Property,

x + 4x + 5x = 180°

10x = 180°

x = 18°

hence, first angle = 18°

second angle = 4 × 18 = 72°

& third angle = 5 × 18 = 90°

Hope it helps!!

Have a great day!!

Answer 2

Let the angles be x

So the angles=1x:4x:5x

We know that the sum of all the angles of a triangle=180°

1x+4x+5x=180

10x=180

$\sf \: x = \frac{180}{10} = 18$

Angles:-

First angle=1x=1×18=18°

Second angle=4x=4×18=72°

Third angle=5x=5×18=90°
