Complete question :

A 25-foot-long footbridge has two diagonal supports that meet in the center of the bridge. Each support makes a 65∘ angle with a short vertical support.

What is the length x of a diagonal support, to the nearest tenth of a foot?

Answer:

13.80 feets

Step-by-step explanation:

Taking either of the triangles formed and attached to the picture, the length of diagonal, x can be obtained using Pythagoras rule :

To obtain x :

Sinθ = opposite / hypotenus

Opposite = 12.5 feets ; hypotenus = x ; θ = 65°

Sin 65 = 12.5 / x

0.9063077 * x = 12.5

x = 12.5 / 0.9063077

x = 13.792225

x = 13.80 feets

Answer:

To determine if the point is a solution, substitute the x value into the right side of the inequality and compare the result with the y value of the point.

- x + 2 = - 1 + 2 = 1

Now - 3 < 1

Thus (1, - 3) is not a solution

Answer:

$4.90

Step-by-step explanation:

Answer:

10 dollars

Step-by-step explanation:

4 / 2.80 = 1.42857142857

so that means 1.42857142857 is the cost of one apple.

1.42857142857 x 7 = 10

so your answer is,

it costs $10 for 7 apples.

Step-by-step explanation:

Answer:

$1507.84

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 3.6%/100 = 0.036 per year,

then, solving our equation

I = 1240 × 0.036 × 6 = 267.84

I = $ 267.84

The simple interest accumulated

on a principal of $ 1,240.00

at a rate of 3.6% per year

for 6 years is $ 267.84.

Answer:

9

Step-by-step explanation:

12x + 17x - 14 + 90 + 2x + 5 = 360

31x = 279

x = 9

Answer:

[tex]x \approx 24\degree [/tex]

Step-by-step explanation:

In triangle BAC, by Pythagoras theorem:

[tex]AC^2 = BC^2 -BA^2 [/tex]

[tex]AC^2 = (15)^2 -(9)^2 [/tex]

[tex]AC^2 = 225 - 81[/tex]

[tex]AC^2 = 144[/tex]

[tex]AC = \sqrt {144} [/tex]

[tex]AC = 12\: cm [/tex]

In triangle ABD,

[tex] \tan \angle ABD =\frac{AD}{AB} [/tex]

[tex] \tan \angle ABD =\frac{5}{9} [/tex]

[tex] \angle ABD =\tan^{-1}\frac{5}{9} [/tex]

[tex] \angle ABD =29.054604099\degree [/tex]

[tex] \angle ABD =29.05\degree [/tex]

Next, in triangle ABC, by sine rule:

[tex] \frac{\sin \angle ABC}{AC}=\frac{\sin \angle BAC}{BC}[/tex]

[tex] \frac{\sin (\angle ABD+\angle DBC) }{12}=\frac{\sin 90\degree}{15}[/tex]

[tex] \frac{\sin (29.05\degree+x) }{12}=\frac{1}{15}[/tex]

[tex] \sin (29.05\degree+x) =\frac{12}{15}[/tex]

[tex]29.05\degree+x = \sin^{-1}\frac{12}{15}[/tex]

[tex]29.05\degree+x =53.130102354\degree [/tex]

[tex]29.05\degree+x =53.13\degree [/tex]

[tex]x =53.13\degree- 29.05\degree[/tex]

[tex]x =24.08\degree [/tex]

[tex]x \approx 24\degree [/tex]

Step-by-step explanation:

If she has 60 tickets and each ride is 3 tickets but she has been on x rides you would do 3x and subtract that from 60.

Answer:

a,c,e

Step-by-step explanation:

60 is the total number of tickets, so b and d are wrong because you are no adding to the total number of tickets.

Answer:

26˚

Step-by-step explanation:

Since there is already two angles (The square in the corner shows that the angle is 90˚)

So subtract 90˚ with 64˚ which is 26˚

Answer:

this whole angle is equal to 90°

so the value of angle b = 90°-64°

so the value of b= 26.

Answer:

x = -3

Step-by-step explanation:

To answer this question, you should first remember that the inside angles of a triangle will always add up to 180 degrees. Therefore, we can make an equation and solve it form there:

55 + 54 + (x + 74) = 180

We add like terms:

109 + (x + 74) = 180

Continue adding like terms:

183 + x = 180

Next, we dubtract to siolate the "x" variable:

x = -3

Hope this helps :)

x=-3

Step-by-step explanation:

To start off, you're going to want to know and understand that all the angles of triangle equal 180 degrees.

Now that we know a triangle equals 180 degrees, lets make an equation. This is equation can be 55+54+74+x=180.

Now, lets combine the like terms in the equation. The equation now becomes 183+x=180.

From here, we subtract 180 from both sides, which would get us x=-3.

To double check that this is correct and that it works, you can plug in the -3 where the x would be.

I hope this helped!! Let me know if you have any further questions.

Answer:

x= -3/2 or x=1.

Step-by-step explanation:

First, make the equation into a factorable form by subtracting 2 from each side to get 2x²+x-3=0. Then factor that into (2x+3)(x-1)=0. Then, you would do 2x+3=0, 2x=-3, x= -3/2. After that, do the second equation x-1=0, x=1.

Answer:

The solution of the given inequality is y>-2.

Step-by-step explanation:

The given inequality is :

2(4y-3) > -22

Using distributive property on LHS of the above inequality.

8y-6 >-22

Add 6 both sides of the inequality

8y-6+6 >-22+6

8y>-16

y>-2

So, the value of y is more than -2.
