Question

two angles of a triangle are equal find the measure of each of the equal angle at the third angle is 25 degree​

Answer 1

77.5°

Step-by-step explanation:

Let the equal angles be x

Then,

x+x+25° = 180°

[Sum of all angles of triangle is 180°]

2x = 180 -25°

2x = 155°

x = 155/2

x = 77.5°

Hence,the two equal angles are 77.5°

Answer 2

Answer:

x+x+25=180(angle sum property )

2x+25=180

2x=180-25

2x=155

x=155/2

x=77.5
