Hello! So the blocks are lined up in rows of 8. When you count the number of rows, there are 10 of them. 3 rows of 8 blocks are shaded out of 10 of them. That's 24 blocks shaded out of 80, because 8 * 10 is 80, and 3 * 8 is 24. Let's divide. 24/80 is 0.3.Let's multiply that by 100 to get it in percent form. 0.3 * 100 is 30. There. 30% of blocks are shaded in the picture.
To solve for c, you divide both sides by -18. If you do that, your answer will be -1/16. So, I think you typed the question wrong. Pretty sure it's the first option.
Answer: angle 1: 62 degrees, angle 2:45 degrees, angle 3: 24 degrees
Step-by-step explanation:
First you need to find the X You know that since its a parallelogram opposite sides are congruent so you would do the following equation
(The work below goes vertical)
2x+3=3x-1
-3x-3I-3x-3
---------------
-x =-4
/-1 /-1
----------------
x= 4
So now that we know x=4 we plug it into the side
4+2=6
Then you multiply is by two since df goes across the whole shape and u get 12
Hope that helps
712/34 divide it then you have your answer :)
