In geometry the four sides of a square are all the same length. one side measures (3x+4) and the perimeter of the square is 76.

To find the perimeter of a square you would multiply the length of one side by 4, so you would now have:

(3x+4) * 4 = 76

Divide both sides by 4:

3x +4 = 19

Subtract 4 from both sides:

3x = 15

Divide both sides by 3:

x = 5

a 12-ft ladder leans against a building so that the angle between the ground and the ladder is 74°. how high does the ladder rea

WINSTONCH [101]

Answer:

12 feet

Step-by-step explanation:

Sometimes, a simple drawing is a great way to start! In the attached drawing, the red line represents the ladder, the brown represents the ground, and the black represents the building!

We want to find the side of the triangle from where the ladder meets the building to where the building meets the ground. This can be found using trigonometric identities, namely sine:

$sin\theta=\frac{opposite}{hypotenuse}$

Plug in known values:

$sin(74^o)=\frac{x}{12}$

Rearrange to isolate the variable:

$x=12sin(74^o)$

Simplify!

$x=11.535140... ft$

Round to the nearest foot:

$x=12ft$

(y+1) +4 rewrite each expression<br><br> i need help plss

QveST [7]

To rewrite, all we have to do is apply the associative property of addition. It allows us to write the expression as <br /><br />y + (1 + 4) <br /><br />we could even take it one step further and combining our terms for<br /><br />y + 5
