Question

i angle por = 90 degree if y:z = 2:3 find the value of x​

Answer 1

Answer:

144°

Step-by-step explanation:

Given angle POR=90°

Also anglePOR+angle ROQ=180°(Linear pair)

=>angle ROQ=90°

Now we know that y:z=2:3

=>2t+3t=90

=>5t=90

=>t=18

therefore y=2t=36

and z=3t=54

Now we see angle x and y form a linear pair

therefore x+y=180°

x+36=180

=>x=144°
