Question

In the adjoining angle, AOB is a straight line. Find the value of x. Hence, find angle-AOC and angle-BOD​

Answer 1

Answer:

x = 27.5, AOC = 77.5, BOD = 47.5

Step-by-step explanation:

3x - 5 + 55 + x + 20 = 180
4x + 70 = 180

4x = 110

x = 110/4 = 27.5
x = 27.5

aoc = 3x - 5
= 3*27.5 - 5
= 82.5-5
= 77.5

bod = x + 20
= 27.5 + 20

= 47.5

Answer 2

Answer:

(3x-5)°+55°+(x+20)°=180°

3x-5°+55°+x+20°=180°

4x+70°=180°

4x=110°

x=110°/4° = 27.5

AOC= 3(27.5)-5 = 82.5-5°=77.5°

BOD = 27.5+20 = 47.5°
