let the other leg be x cm.
(5)^2+(x)^2=(12)
25+(x)^2=144
(x)^2=144-25
x=√119
x=10.9
Answer:
42 units squared
Step-by-step explanation:
break it up into smaller shapes. if you split the big shape at y = 2 and at y=-2, you'll get two triangles and one rectangle.
so the area of the rectangle = l x w
= 4 x 7
= 28
the area of the triangle is ( l x w )/2
= (7 x 2)/2
= 7
the other triangle is the same too
so the area of that is also 7.
now add all areas,
7+7+28 = 42
Answer:
Button #4. The last button. 8p = t.
Step-by-step explanation:
This is because there are 8 pieces of string, and p is equal to the length of one string, so one string times 8 is the total length of all the strings.
Length (L): 3w
width (w): w
Perimeter (P) = 2L + 2w
32 = 2(3w) + 2(w)
32 = 6w + 2w
32 = 8w
4 = w
Length (L): 3w = 3(4) = 12
Answer: width = 4 meters, length = 12 meters
Just be patient: y = -sqrt(8.41) = calculator (negative value) and so on. The last one is 0! :)
