Question

find the angel of the triangle in degree and radian ​

Answer 1

AS ONE ANGLE OF RIGHT ANGLE TRIANGLE IS 90° , THUS SUM OF OTHER ACCUTE ANGLES IS 90°...LET ANGLES BE 4X & 5X

NOW, 4X+5X= 90 => 9X = 90 => X = 10

SO ANGLES ARE 40° & 50° RESPECTIVELY.... NOW USE FORMULAE TO CONVERT DEGREE TO RADIAN.....
