Question

which of the following is true of the values x and y in the diagram below ?
a y b y>x
c y+x=1
d y/x=1

Answer 1

Step-by-step explanation:

theta =π/4= 45°

x= cos45°

=1/√2

y=sin45°=1/√2

So,x=y

or,y=x

or, y/x =1

optionD

Answer 2

The statement true about the circle is mathematically given as

x/y=1

Option D is correct

What is a circle?

A circle is simpy a round figure with a circumference made up of points equidistant from a fixed point.

Generally, the equation for the angle  is mathematically given as

\theta =π/4

Therefore

\theta= 45°

In conclusion, when x= cos45°

y=sin45°

y=1/√2

Hence x=y

giving x/y=1
