The answer is will be zero because there is no way else
(1,3)(4,-3)
slope = (-3-3) / (4 - 1) = -6/3 = -2
y = mx + b
slope = -2
use either of ur points....(1.3)...x = 1 and y = 3
now sub and find b, the y int
3 = -2(1) + b
3 = -2 + b
3 + 2 = b
5 = b <===
Answer:
27 and 36
Step-by-step explanation:
x + (x - 9) = 63
2x - 9 = 63
add 9 to both sides
2x = 72
Divide both sides by2
x = 36
x - 9 = 36 - 9
x - 9 = 27
Answer:
<em> Length of guy wire is 590.6 ft</em>
Step-by-step explanation:
The complete question is
A radio transmission tower is 210 feet tall. How long should a guy wire be if it is to be attached 8 feet from the top and is to make an angle of 20° with the ground. Give your answer to the nearest tenth of a foot.
height of tower = 210 ft
8 ft fro the top leaves 210 - 8 = 202 ft to the ground
This is an angle of elevation problem
the opposite is 202 ft
hypotenuse = ?
angle is 20°
using sin ∅ = opp/hyp
sin 20° = 202/hyp
0.342 = 202/hyp
hyp = 202/0.342 = <em>590.6 ft this is the length of the guy wire</em>
5 and 10.
5 × 10 = 50
5 + 10 = 15
