Question

If one angle is 160 find two angle of triangle

Answer 1

Step-by-step explanation:

let the angle be x

there dore x + x + 160 = 180degree

2x= 180 - 160 =20

therefore 20 divided bh 2 is equal to 10

Answer 2

Answer:

First angle = 160°

Second angle = 10°

Third angle = 10°

Step-by-step explanation:

Given :

One angle of triangle = 160°

To find :

The rest two angles of the triangle

Taken :

Let the other two angles be x

So , to the both angles use this formula -:

$\boxed{\tt{x+x+{160}^{\circ}={180}^{\circ}}}$

Taken 180° because the sum of all the angles of the triangle is 180° .

After finding the value of x that will be the value of both the angles of the triangle .

Solution :

$\leadsto\tt{x+x+{160}^{\circ}={180}^{\circ}}$

$\leadsto\tt{2x+{160}^{\circ}={180}^{\circ}}$

$\leadsto\tt{2x={180}^{\circ}-{160}^{\circ}}$

$\leadsto\tt{2x={20}^{\circ}}$

$\leadsto\tt{x=\cancel{\dfrac{{20}^{\circ}}{2}}}$

$\leadsto\tt{x={10}^{\circ}}$

So ,

First angle = 160°

Second angle = 10°

Third angle = 10°
