Question

Eash of the two equal angles of a triangle is twice the third angle. Find the angles of the triangle​

Answer 1

Answer:

Step-by-step explanation:

assuming (a,b,c=angle)

a+b+c = 180

c=b

c=a*2  

as b=c we can write a+2a+a

Sorry (uh for making it confusing just skip it)

a+2a+a = 180

4a = 180

a = 180/4

a=45 degree

------------------

the angles are 45 , 45 and 90

Let, the third angle be r°, then each of the other equal angles will be 2a°.

Now, using Angle-sum-property, we have,

$⇒x + 2x + 2x = 180°$

$⇒5x = 180°$

$⇒ x = \frac{180°}{5}$

$⇒x = 36° \: so \: 2x = 2 \times 36 = 72°$

$hence \: angles \: of \\ \: the \: triangles \: are \: x = 36° \: 2x$

$= 72° ,2x = 72°$

ANS. 36° , 72° , 72°
