How can i find the value of each variable

x=20

Step-by-step explanation:

So, they are vertical angles so they would be EQUAL.

The equation you would use to solve for 'x' would be:

3x=80-x

Then, you would solve for x. First you would need to get all the x's on the opposite side of the numbers.

3x=80-x

Add x to both sides

4x=80

Then, you would have to divide on both sides.

4x=80

Divide by 4 on both sides

x=20

Then, if you need to find out what the angles would be, just plug x in.

3(20) = 60

80-(20) = 60

Hope this helped!! :)

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.

step-by-step explanation:

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
