Answer:
the second one
Step-by-step explanation:
So the formula for the area of a trapezium is
area = (a + b)/2 * h
*a is the short side
* b is the long side
*h is the height
so let's plug in the values we already know: area, long base, short base. Here's how the formula looks now...
6550 = (150 + 85)/2 * h
*so, we need to find 'h'
use algebra to find it.
6550 = (235/2) * h
6550 = 117.5 * h
6550/117.5 = h
h = 55.74 (approx)
The answer is x>-2 first you just move the -1 by adding 1 to both sides. Then you get 4x>-8 then you must isolate the x by dividing the 4 on both sides. After you divide it you will have just x on one side of the inequality and -2 on the other side. this will leave you with the inequality x>-2
Answer:
53
Step-by-step explanation:
they are a linear pair so x + 2x + 21 = 180 so you subtract 21 from both sides, combine x and 2x then divide by 3 to get 53
