Answer:

Change the angle measures to 90°

Step-by-step explanation:

x = length of fourth side in quadrilateral ABCD

Have a look at the attached image I've posted. I made a chart that lines up the side lengths from largest to smallest. Note how the first two items in the bottom row are blank. We don't know these values and we don't need to find out in order to find x.

Based on the last two columns of that table, we can form the proportion below, which is then used to isolate x.

30/12 = x/6

30*6 = 12*x ... cross multiply

180 = 12*x

12*x = 180

x = 180/12 ... divide both sides by 12

x = 15

Answer:

L = 25

Step-by-step explanation:

Let's call the Length x and width x - 15 since the width is 15 less than length

Eric needs 70 of fencing in total, the perimeter of a rectangle is calculated by adding all sides

x + x + (x - 15) + (x - 15) = 70 add like terms

4x - 30 = 70 add 30 to both sides

4x = 100 divide both sides by 4

x = 25

Shane decided to dig his garden.On the first fine day,he dug 1/3 of it.On the second day he dug only 1/4 of it before it started
jeka94

Answer:

I think 1/4

Step-by-step explanation:

So, you first should find a common denominator so you can add the fractions together.

So, 1/4 + 1/3 + 1/6 becomes 3/12+4/12+2/12.

Add that up, you get 9/12.

Simplify.

9/12 = 3/4

3/4 is how much is dug out. 4/4 - 3/4 is 1/4. That's how much for digging is left, I believe.
