8 0

Answer:

D. x=4

Step-by-step explanation:

We can solve this with the Pythagorean Theorem for the right triangle that we can see (which is half of the triangle).

The bottom length is 3 and the hypotenuse is 5.

The Pythagorean Theorem is a²+b²=c².

We can plug this in:

3²+x²=5²

9+x²=25

x²=16

x=4

A flagpole has a height of 10 yards. It will be supported by 3 cables, each of which is attached to the flagpole at a point 4 ya
Contact [7]
Pytagorean theorem

height10
attached at 10-4=6 yards from bottom
8 yards from base to away


a^2+b^2=c^2
a and b are side legnths and c=hypotonuse
so therfore we are given a and b and we must solve for c


so
6=height
8=base

6^2+8^2=c^2
36+64=c^2
100=c^2
square root
10=c

so therfor the legnth of each cable is 10 yards
3 cables so 3 times 10=30

30 yards needed

4. A parking lot of rectangular shape has a perimeter of 420m. The width is three-fourths
Lena [83]

Answer:

Width: 90m

Length: 120m

Step-by-step explanation:

Width = 3/4x

Length = x

2(3/4x) + 2x = 420m

6/4 x + 2x = 420m. (6/4 + 2 = 7/2)

7/2x = 420m

7x = (420)*(2)

x = 840/7 = 120

Width = (120)*(3/4) = 90

Length: 120

2(90)+2(120)= 420m
