Question

If AB and CD intersect at O.If a:b=4:5 Find a,b,c,d​

Answer 1

Step-by-step explanation:

Given If AB and CD intersect at O.If a:b=4:5 Find a,b,c,d

• So there is a figure wherein two rays AB and CD intersect at a point o.
• Now since AOB is a straight line a + b = 180 degree (linear pair of angles)
• According to the question a : b = 4 : 5
• Or 4 + 5 = 9
• Now a = 180 x 4/9
• Or a = 80
• Also b = 180 x 5/9
• Or b = 100
• Now c = a and d = b (because they are vertically opposite angles)
• So we get a = 80, b = 100, c = 80 and d = 100.
