In the adjoining figure, AOB is a straight line. Find the value of x. Hence, Find And


Answer :

X=27.5, =77.5°=47.5°


AOB is a straight line


Therefore, + COD + = 180°


(3x - 5)° + 55° + (x + 20)° = 180°


3x - 5° + 55° + x + 20° = 180°


4x = 180° - 70°


4x = 110°


x = 27.5°


= (3x - 5)°


= 3×27.5 – 5 = 77.5°


= (x + 20)°


= 27.5 + 20 = 47.5°
