Answer:

The answer to your question is 39 lb

Step-by-step explanation:

Data

Force = 60 lb

angle = 40°

vertical component = ?

Process

To answer this question, we must imagine a right triangle where the force gave is the hypotenuse, and the vertical component will be the opposite side to the 40° angle.

1.- Look for a trigonometric function that relates the opposite side and the hypotenuse

          sin Ф = Opposite side / hypotenuse

- Solve for Opposite side

          Opposite side = hypotenuse x sin Ф

- Substitution

          Opposite side = 60 x sin 40

- Simplification

          Opposite side = 60 x 0.64

- Result

          Opposite side = 38.56 ≈ 39 lb

lisov135 [29]

Answer:

change the order, so the terms line up

20g+15m=300

g+m=17

multiply the second equation by 20, so the 20g and -20g can cancel out

20g+15m=300

-20g-20m=-340

solve the equation, then divide -5 to both sides to isolate the m

-5m=-40

m=8

substitute the value of m into one equation to find the other value

g+8=17

g=9

write them in ordered paired form

(9, 8)

Step-by-step explanation:

hope this helps :)

Two sides of a triangle have the same length. The third side measures 3 m less than twice that length. The perimeter of the tria
Readme [11.4K]

Answer:

two sides have the length of 7m

third side is 11m

Step-by-step explanation:

perimeter is the sum of all sides

let 'n' = length of congruent sides

let '2n - 3' = length of third side

25 = n + n + 2n - 3

25 = 4n - 3

28 = 4n

n = 7m

2(7) - 3 = 11m

Answer:

(-2, -4), (-1, -1), (0, 0), (1, -1), (2, -4)

Step-by-step explanation:

You plug in x values to get the y values are dot-in the points!

y = -x^2

You plug in -2 and get -(2)^2 = -(4) = -4

Same thing with all other values.
