use given information, such as angles
Could we see a picture?
Given the dimensions, use the formula: A = bh
The bottom number is a 6
Well, you have 4 right triangles and you are given the base and height of each triangle. So use A = 1/2 bh four times and add them together
I got an answer of 63. Is that correct
I forgot to divide by 2
So if I divide by 2, I get 31.5
That's what I got.
Thanks Mertsj and everyone else.
The midpoint of line QR is M (-2,-6). One endpoint is R (4,-5). Find the coordinates of the other endpoint.
From 4 to -2 is left 6. go left 6 more to get to the other end. That would be -8 From -5 to -6 is down 1. Go down one more to get to the other end. That would be -7 So (-8,-7) Now graph it to see if it makes sense.
Yes, we got the same thing. This is a rise run problem. Thank you again
In the diagram, PQRS is a rhombus. What are the values of x and y?
What is this thing?
so all sides are equal. So write that 2x=x+5 and solve it.
2x = x + 5 2x -x = 5 x = 5
Is that all? It feels like I need to do more
How do I find y?
The diagonals of a rhombus are perpendicular and so now that you know one of the sides, you can use the pythagorean theorem
So the answer is 6?
Thanks again. That's all for tonight. Again I thank you. Am I able to come on this site every night?
you can come whenever you want
So the answer is 6?
yes y = 6
It's a 6-8-10 right triangle. A multiple of the famous 3-4-5- pythagorean triple.
