Consider the following diagram below.

Find the values of x and y.

x = 17, y = 22.5

Step-by-step explanation:

In this question, we are asked to calculate the value of y and x.

Now, the circle theorem to use is that opposite angles of a cyclic quadrilateral are supplementary. This means that they add up to be 180 degrees.

Thus, mathematically;

(4x-3) + (6x+13) = 180

and also;

5y + 3y = 180

Thus, solving both equations one after the other, we can get the values of x and y.

Let’s start with the first;

4x -3 + 6x+13 = 180

10x + 10 = 180

10x = 180-10

10x = 170

x = 170/10

x = 17

For the second equation;

8y = 180

y = 180/8

y = 22.5

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !

step-by-step explanation:

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
