Answer:
92,320,000
Step-by-step explanation:
100,000,000 - 7,680,000 = 92,320,000
branliest? :)
Step 1: find two numbers that multiply to give ac ( in other words a x c ) and add to give b
step 2: rewrite the middle with those numbers
step 3: factor the first two and last two terms separately
step 4: if you’ve done this correctly, your two new terms should have a clearly visible common factor
and then you’re done! hope this helps!

Answer:
a. 80.83 ft b. 40.42 ft
Step-by-step explanation:
Let h = height of pole = 70 ft, L = length of cable and x = distance of cable on ground to pole and Ф = angle between cable and ground.
a) How long is the cable?
Since L, h and x form a right-angled triangle with angle Ф and h being the opposite side to Ф and L being the hypotenuse side, by trigonometric ratios,
sinФ = h/L
L = h/sinФ
L = 70 ft/sin60°
L = 70 ft/0.8660
L = 80.83 ft
b) How far from the pole should the cable be attached to the ground?
Since L, h and x form a right-angled triangle with angle Ф and h being the opposite side to Ф and x being the adjacent side, by trigonometric ratios,
tanФ = h/x
x = h/tanФ
x = 70 ft/tan60°
x = 70 ft/1.7321
x = 40.42 ft
