Question

Someone help with this thank you if you help.

Answer 1

The answer you are looking for is 36. The sum of all angles within a triangle will always be 180°. Since we are given the one angle of 54° and since we know that we are looking at a right triangle (a triangle that as a 90° angle, as indicated by the square symbol) we can add 54 and 90 to get 144°. From here just subtract 144 from 180. This will give your final solution of 36°. If you have any further questions about this topic just let me know!

Answer 2

⇒ Sim of all the three interior angles of a triangle is 180°,Meaning

: In the triangle in the picture we have three angle and given is two known angle and 1 unknown angle angle 1.

Note this is a right-angled triangle since it is also shown by the sign of of angle 90°

54°+90°+ ∠1=180°

144°+∠1=180°

∠1=180°-144°

∠1=36°

From the calculation ∠1 is equal to 36°
