Question

if two angles of a triangle are 30 డిగ్రీస్ అండ్ 45 degrees then find its third angle​

Answer 1

Answer:

Given :-

• Two angles of triangle is 30⁰ and 45⁰

To Find :-

Third Angle

Solution :-

As we know that

Sum of all angles in a triangle is 180⁰

Let the third angle be x

$\sf \: 180 = 30 + 45 + x$

$\sf \: 180 = 75 + x$

$\sf \: 180 - 75 = x$

$\sf \: 105 = x$

Therefore,

Third angle of triangle will measure 105⁰

Answer 2

Answer:

Third angle is 105°

Step-by-step explanation:

Let the third angle be x

$\implies$ $\sf{30+45+x = 180}$

(Angle sum property of triangle)

$\implies$ $\sf{ 75 + x = 180}$

$\implies$ $\sf{ x = 180 -75}$

$\therefore$ $\boxed{\sf{ x = 105°}}$
