Question

The sum of two angles of a triangle is equal to its third angle. Determine the measure of the third angle.

Answer 1

Answer:

90°

Step-by-step explanation:

let the two angles be x degree each

and third angle be y

therefore according to given condition,

x+x=y

we know that

sum of all angles of a triangle is180 degrees

therefore,

x+x+y=180

substituting x+x=y we get

y+y=180°

2y=180

y=90°
