Brigid has a 25-foot ladder she will use to paint the side of her house. What angle does the ladder need to make with house so s

Answer:

The answer to your question is the letter D) 46°

Step-by-step explanation:

Data

length = 25 ft

Opposite side = 18 ft

Angle = Ф

To solve this problem, use trigonometric functions. The trigonometric function that relates the Opposite side and the hypotenuse is sine.

Sin Ф = Opposite side / hypotenuse

-Substitution

sin Ф = 18/25

-Simplification

sin Ф = 0.72

-Result

sin⁻¹ Ф = 0.72 = 46°

-x - 1 = 221 + 2x <br> plzzzzzzzzz help

Otrada [13]

$Simplifying
-1x + -1 = 221 + 2x

Reorder the terms:
-1 + -1x = 221 + 2x

Solving
-1 + -1x = 221 + 2x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2x' to each side of the equation.
-1 + -1x + -2x = 221 + 2x + -2x

Combine like terms: -1x + -2x = -3x
-1 + -3x = 221 + 2x + -2x$
$Combine like terms: 2x + -2x = 0
-1 + -3x = 221 + 0
-1 + -3x = 221

Add '1' to each side of the equation.
-1 + 1 + -3x = 221 + 1

Combine like terms: -1 + 1 = 0
0 + -3x = 221 + 1
-3x = 221 + 1

Combine like terms: 221 + 1 = 222
-3x = 222

Divide each side by '-3'.
x = -74

Simplifying
x = -74$

Help... anyone????????

katovenus [111]

Since they both have 3x terms subtract the second from the first to get rid of the x terms...

3x+2y=10
-3x+y=-13
__________
3y=-3

y=-1, which makes 3x+2y=10 become: 3x-2=10 so

x=4

So the solution is the point (4, -1)

Find the degree measure of each angle in the triangle.

Alex777 [14]

Answer:

∠R = 56°
∠Q = 90°
∠S = 34°

Step-by-step explanation:

The given triangle is a right angled triangle.

So, the angles in the triangle are :

90°
(2x + 38)°
(5x - 11)°

Solving according to <u>angle sum property</u>,

Sum of all angles in a triangle is 180°

$\longrightarrow$ 90° + (2x + 38)° + (5x - 11)° = 180°

$\longrightarrow$ 117° + 7x = 180°

$\longrightarrow$ 7x = 180° - 117°

$\longrightarrow$ 7x = 63°

$\longrightarrow$ x = 9

Angles =

$\longrightarrow$ 2(9) + 38

$\longrightarrow$ 56°

$\longrightarrow$ 5(9) - 11

$\longrightarrow$ 34°

∠R = 56°
∠Q = 90°
∠S = 34°

The angles are 56°, 90° and 34°.

The ratio of men to women working for a company is 3 to 5. If there are 120 women working for the company, what is the total num

Xelga [282]

Answer: 192 people

Step-by-step explanation:

We can set up a ratio.

Let x be the number of men working in the company.

$\frac{3 men}{5 women} = \frac{xmen}{120 women}$

We can cross umltiply.

360 = 5x

x = 72 men.

Therefore, the total number of employees = 120 women + 72 men

= 192 people.
