Question

if two angles of a triangle are 65 degree and 75 degree then find out the measure of third angle​

Answer 1

Answer:

Let the remaining angle be x

As we know,

X + 65+45=180(sum of angle of triangle)

X=180-110

So, x= 70

Answer 2

Step-by-step explanation:

One of the angles of a triangle is 65 o . Find the remaining two angles, if their difference is 25 o .

ANSWER

Let one angle be ∠x

∴ other angle is ∠x+25 o

Now, We know, by angle sum property, the sum of all angles of a triangles is 1800 .

⟹x+x+25 o +65 o =180 o

⟹2x=180 o −90 o

⟹x=45 o

Thus, the angles are 45o and 70 o
