Question

Two of the angles in a triangle measure 51° and 25°. What must be the measure of the third angle?

Answer 1

Answer:

The third angle must be 104

Step-by-step explanation:

The last angle is found by adding 51 and 25 and the subtracting it from 180

Answer 2

Answer:

104°

Step-by-step explanation:

According to angle sum property of a triangle , sum of all the angles of triangle is equal to 180°.

So, let the third angle be 'x'. According to angle sum property of triangle ,

$x + 25 + 51 = 180$

$= > x + 76 = 180$

$= > x = 180 - 76 = 104$
