Question

if two of the angles of a triangle are 78 and 26 the third angle will be.​

Answer 1

Answer:

sum of internal angles of a triangle =180°

answer =76°

Step-by-step explanation:

1st angle=78°

2nd angle =26°

3rd angle=x

78+26+x=180°

104+x=180°

x=180°-104°

x=76°

answer is the third angle is 76°

Answer 2

Answer:

The other angle of the triangle is 76°

Step-by-step explanation:

let other angle of triangle be x

then,

x+78+26=180° (angle sum property)

x+104=180

x=180-104

x=76
