Question

One acute angle of a right triangle is 36 degree find the other

Answer 1

let A be acute angle of a right triangle is 36
B be 90
C=?
A+B+C=180
36+90+C=180
C=180-126
C=54

Answer 2

Let the unknown angle be x°

We know,Total internal angle of a triangle is 180°.


Given,
<1=90°
<2=36°

Therefore,<1+<2+<3=180°

That is,90°+36°+x°=180°
x°=54°


Therefore, the required angle is 54°.
