1 answer:
Nuetrik [128]4 years ago
7 0

Answer:

17.96956941 =x

Step-by-step explanation:

tan theta = opposite side/ adjacent side

tan 38 = x /23

Multiply each side by 23

23 tan 38 = x/23 * 23

23 tan 38 = x

17.96956941 =x

Factor this polynomial expression. 3x2 - 12x + 12
harkovskaia [24]

Answer:

(3x-6)(x-2)

Step-by-step explanation:

To factor this expression, you should divide the 12x into parts.

3x - 6x - 6x +12 works,

so factor 3x^2 and -6x = 3x(x-2)

then factor  6x and 12 to match the first expression, -6(x-2).

Both expressions have (x-2) in common, so you can factor the two resulting expressions: (3x-6)(x-2).

Here are sketches of four triangles.
Temka [501]

Answer:

x ≈ 2.29 cm

Step-by-step explanation:

From the picture below we are given a right angle triangle and asked to find the value of x. We can use the SOHCAHTOA principle to find the side x.

Base on the angle given the adjacent side of the triangle is x while the hypotenuse is given as  4 cm. Let's find the value of x .

cos 55° = adjacent/hypotenuse

cos 55° = x/4

cross multiply

x = 4 cos 55°

x = 4 × 0.57357643635

x = 2.2943057454

x ≈ 2.29 cm

What is a simple rule for adding and subtracting like fractions
konstantin123 [22]

Here is you're answer:

One of the most simple rules when solving fractions is to "find the common denominator."

Example:

  • \frac{1}{2} + \frac{1}{2} =
  • Find the common denominator:
  • Common denominator is 2:
  • 1 +1=2
  • = \frac{2}{2} = 2

So, in order to solve fractions you first have to find the common denominator of each fraction, then you have to add or subtract the numerators to equal you're answer.

Hope this helps!
