Oh. It's rounding. So, for example, depending what you were told to round to, the second problem would be 760-330=430
Answer:
21
Step-by-step explanation:
21
The 30,60,90 - the hypotenuse is equal to twice the length of the shorter leg , the hypotenuse side =2x , the shortest side =x and the straight side is x square root 3

Answer:
640 units squared
Step-by-step explanation:
The shape below is a trapezoid.
The formula for the area of a trapezoid is average of the bases times the height.
The bases are the parallel lines that make up 2 of the sides of the trapezoid.
The height is the line dotted line that creates right angles and is the distance between the two bases.
The bases are 24 and 40.
To find the average, we add them together and divide by 2
(24+40)/2=64/2=32
Now, we multiply 32 by the height, which is given as the length of 20.
32*20=640
the area of the trapezoid is 640 units squared
Hope this helps!
