Answer:
1
Step-by-step explanation:
once we know 2 of the angles we can find a third. once we have all 3 angles we only need one side length to tell us how big it is.
Bonus question: How many triangles can be drawn with one 3 inch side ,a 4 inch side, and a 20ºangle?
Answer:
She can fill 9 containers
Step-by-step explanation:
you do 6 3/4 dived by 3/4 and you get 9
The decimal would be .95 and the fraction would be 95/100 I believe
NOT 100% sure
Hope it helps

Answer: x^2-3x+36</h3>
=========================================
Explanation:
The larger rectangle has area of (x+1)(x+1) = x^2+2x+1 through the use of the FOIL rule or distribution
If you use distribution, then it might help to let y = x+1 so we'd have y(x+1) lead to xy+1y which becomes x(x+1)+1(x+1). From there it might be easier to see how to get x^2+2x+1 after everything distributes again and simplifies.
The smaller rectangle has area 5x-35 which is found by distributing 5(x-7)
To get the shaded area, we subtract the two rectangle areas found above
shaded area = (larger area) - (smaller area)
shaded area = (x^2+2x+1) - (5x - 35)
shaded area = x^2+2x+1 - 5x + 35
shaded area = x^2-3x+36
