Question

In fig. ray OC stands on a line AOE if x : y = 2:1
Z: W=1:2
And < AOC = R find <BOD
b
y
A​

Answer 1

Answer:

<BOD=60°

Step-by-step explanation:

let x:y be 2:1 as 2x,1x along with z:w be 1:2 as 1x,2x and <AOC=90°(given),<EOC=90°(linear pair)

2x+1x=90°

3x=90°

x=30°

so,

<BOD=y+z

<BOD=1x+1x

<BOD=2x

<BOD=2×30°

<BOD=60°
