Question

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

Answer 1

Answer:

90°

Step-by-step explanation:

Consider △ABC,

Then according to the given condition, ∠A=∠B+∠C

Sum of all the interior angles of the triangle is 180

o

Hence, ∠A+∠B+∠C=180

o

2∠A=180

o

⇒∠A=90

0

Answer 2

Answer:

the sum of triangle is 180 if two angles are 45 and 45 so sum is 90 thir angle is 90 hence 90+45+45 = 180
