Answer:
Angles are 36,54 and 90 degrees
Step-by-step explanation:
Since it is a right triangle, one angle is obviously 90° and the sum of the other two will also be 90° (since a triangle's angles are 180°). One is X and the other is 18+X, sum both equations and equal them to 90°, and when you get X substitute in the equations
Answer:
90°, 54° and 36°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Let x be the smallest angle then the other angle is x + 18, hence
x + x + 18 + 90 = 180, that is
2x + 108 = 180 ( subtract 108 from both sides )
2x = 72 ( divide both sides by 2 )
x = 36
thus x + 18 = 36 + 18 = 54
The 3 angles are 90°, 54° and 36°
