20^2 + 21^2 = 27^2
400 + 441 = 729
881 = 729 (does not equal)
Not a right traingle
22 is the answer because I just did it
I hope that this made sense to you.
number 4 is x = 9 and number 5 is x = 10
40m to the 2nd power when doing the math its 40m to the 2nd power and then you get ur answer :)
Answer:
f=6
g=8
Step-by-step explanation:
If ABCE is a trapezium, AD is parallel to BC, and angle C is a right angle, ABCD must be a rectangle. You know that since ABCE has an area of 60 and ABCD has an area of 48, ADE must have an area of 12. Because the area of a triangle is bh/2, AD must be 6 and therefore f must be as well. Since ABCD has an area of 48, g must be 48/6=8. Hope this helps!
