Step-by-step explanation:
By phythagorous theorem,
AC²=AB²+BC²
AC²=36+64
AC²=100
AC=root of 100
AC=10
8.5cm · 250,000 = 2,125,000cm
1m = 100cm therefore 1cm = 0.01m
2,125,000cm = 2,125,000 · 0.01 = 21,250m
1km = 1,000m therefore 1m = 0.001km
21,250m = 21,250 · 0.001km = 21.25km
Answer: 21,250m = 21,25km
Answer: the answer is 120 for it the area but that is not on the answer list.
Step-by-step explanation:
Answer:
B. all of these are true
Step-by-step explanation:
The Square is a rhombus because all the sides of a square are equal in length. Even, the diagonals of both square and rhombus are perpendicular to each other and bisect the opposite angles. Therefore, we can say the square is a rhombus.
Hope this helped!!
Answer:
a = (r/x) -b
x = -14
Step-by-step explanation:
r=x(a+b)
Divide each side by x
r/x = a+b
Subtract b
r/x -b = a
x/2=-7
Multiply each side by 2
x/2*2 = -7*2
x = -14
