Question

in a right anght angle d triangle,if one angle is 45 degree then the measure of the third angle is _____ degree*​

Answer 1

Answer:

45 degree

Explanation:

According to the question.

90 + 45 + x = 180 (Angle sum property)

x = 180 - 135 = 45

Answer 2

It's an right angled triangle. So, measure of a angle = 90°

Given, Measure of 2nd angle = 45°

We know, Sum of all angles of a triangle = 180°

Here, Let the angle = x°

So, 90°+45°+x° = 180°

135x° = 180°

x = 180°-134°

x = 46°

So, Measure of 3rd angle is 46°
