In a right triangle where one of the angles measure 30° what is the ratio of the length of the side opposite the 30°angle to the

kifflom [539]

Answer:

The ratio of the length of the side opposite the 30°angle to the length of the side opposite the 90°angle is 1:2.

Step-by-step explanation:

Consider ABC, With 90° angle at B and 30° angle at C.

To find: AB:AC=?

Solution:

AB = perpendicular of the right angled triangle

AC = Hypotenuse of the triangle

$Sin\theta =\frac{Perpendicular}{Hypotenuse}$

$sin\theta =Sin 30^o=\frac{AB}{AC},(Sin 30^o=\frac{1}{2})$

$\frac{1}{2}=\frac{AB}{AC}$

The ratio of the sides ,AB:AC = 1:2.

Hence,the ratio of the length of the side opposite the 30°angle to the length of the side opposite the 90°angle is 1:2.

If f(x)= negative -3x +4 and g(x)=2 solve for the value of X for the which f(x) =g(x) is true

Sever21 [200]

Answer:

x = -2/3

Step-by-step explanation:

Step 1: Convert signs

f(x) = -(-3x) + 4

f(x) = 3x + 4

Step 2: Set f(x) and g(x) equal to each other and solve for <em>x</em>

3x + 4 = 2

3x = -2

x = -2/3

And we have our final answer!

Estimate the perimeter and the area of the shaded figure to the nearest whole number.

soldier1979 [14.2K]

Answer:

Step-by-step explanation:

The area and perimeter of the given shaded figure are respectively 33.12 unit² and 20.56 units.

Area and perimeter-based problem:

What information do we have?

Radius of semi-circle = 8 / 2 = 4 unit

Length of remain Rectangle = 8 unit

Width of remain Rectangle = 2 unit

Perimeter of shaded figure = πr + (l + 2b)

Perimeter of shaded figure = (3.14)(4) + [4 + (2)(2)]

Perimeter of shaded figure = 12.56 + 4 + 4

Perimeter of shaded figure = 20.56 units

Area of shaded figure = πr²/2 + lb/2

Area of shaded figure = (3.14)(4)²/2 + (8)(2)/2

Area of shaded figure = (3.14)(8) + 8

Area of shaded figure = 25.12 + 8

Area of shaded figure = 33.12 unit²

for the expression n(2n+4n^2-5-3n), use the distributive property to write an equivalent expression in standard form

Ronch [10]

$\text{distributive property:}\ a(b+c)=ab+ac\\\\2n+4n^2-5-3n=4n^2+(2n-3n)-5=4n^2-n-5\\\\n(2n+4n^2-5-3n)=n(4n^2-n-5)=(n)(4n^2)+(n)(-n)+(n)(-5)\\\\=\boxed{4n^3-n^2-5n}$
