Given:

A cyclic quadrilateral and two opposite angles of it in the form of y.

To find:

The value of y.

Solution:

We know that, opposite angles of a cyclic quadrilateral are supplementary angles. So, their sum is 180^\circ.

The measures of opposite angles of cyclic quadrilateral are y and 2y. So,

y+2y=180^\circ

3y=180^\circ

Divide both sides by 3.

y=\dfrac{180^\circ}{3}

y=60^\circ

Therefore, the value of y is 60^\circ.

3 out of 5 picks are orange. if 12 picks are orange haw many picks are in all
xxTIMURxx [149]

Answer:

There were 20 picks total

Step-by-step explanation:

We can use a proportion to solve this problem.  Put the orange picks on top and the total picks on bottom

3 orange         12 orange

-------------- =   ---------------

5 total                x total

Using cross products

3x = 5*12

3x= 60

Divide each side by 3

3x/3 = 60/3

x = 20

There were 20 picks total
