A rhombus is the parallelogram with perpendicular diagonals. All
<u>Correct statements, reasons:</u>
- A - adjacent angles are supplementary
- B - opposite sides are parallel
- C - diagonals are perpendicular
- E - opposite sides are congruent
<u>Incorrect statements, reasons:</u>
- D - opposite angles are congruent, but not supplementary
- F - diagonals are not congruent, it would be square not rhombus

Step-by-step explanation:
The ratio of sugar to flour is 2 is to 3 cups
Answer:
see below
Step-by-step explanation:
sqrt(77)
8^2 = 64
9^2 = 81
It is closer to 9
We know it is between 8.5 and 9
8.8^2 = 77.44
This is a good approximation
Answer: 276
Step-by-step explanation:
multiply 1/3 by 4/4 to make it similar to 5/12 that way you can add them. because the denominator is different from each other you can’t add them. once you do that you get 4/12, you then add 5/12 and that equals 9/12. in order to get to 12/12 you need 3/12 more. this 3/12 represents the 69 guest that chose vegetarian. the 5/12 represents the the guest who chose chicken and the 4/12 represents the ones who chose beef. now that you know 69 people is the same as 3/12 of all the guest. you then realize that 9 is divisible by 3. so you multiply 69 by 3 because 3 goes into 9 3 times. which gives you 207. 207 represents 9/12. and we already know 69 represents 3/12. so you add them together and get 276. sorry if that was confusing but that’s the best way i can explain it.
Divide the shape into 2 rectangles:
Area = Length x width
1 : 7 x 30 = 210
2: (25 -7) x (30-20) = 18 x 10 = 180
Total area = 210 + 180 = 390 square feet.
