HELP ME !!! GEOMETRY

Mathematics
1 answer:
ahrayia [7]2 years ago
6 0

Answer:

  (b)  33

Step-by-step explanation:

The side opposite x° and the hypotenuse are given. That means the relevant trig relation is ...

  Sin = Opposite/Hypotenuse

  sin(x°) = 6/11

The value of the angle is found using the inverse sine function:

  x° = arcsin(6/11) ≈ 33.056°

  x ≈ 33

_____

<em>Additional comment</em>

If you recall, the side length ratios of the "special" 30°-60°-90° triangle are 1:√3:2. Here, you have a shortest:longest side ratio that is 6:11 ≈ 6:12 = 1:2. This means the angle will be only slightly greater than 30°.

How would you graph (on a number line) (x-8)(x-8)&lt;0??
Marta_Voda [28]

Answer:

  The graph is the empty number line (no solution)

Step-by-step explanation:

Your expression is (x-8)² < 0. There are no real numbers that give a negative value when squared. There is NO SOLUTION. The graph is empty.

_____

<em>Comment on quadratic inequalities</em>

In general the inequality (x-a)(x-b) < 0 will have a solution when one factor is negative and the other is positive. In general, that will be the case for values of x that are strictly between <em>a</em> and <em>b</em>. In your inequality, that would require you graph numbers that are between 8 and 8. There are none.

What is a TENS fact in math?
tamaranim1 [39]

The multiples of ten quantity or value of 10 in maths.

What is a TENS fact in math?

Your child can learn addition facts by using multiples of ten to help them understand the quantity or value of 10 in maths. I discussed the tens complement method for learning basic addition and subtraction concepts with sums or minuends more than 10, along with some of the many advantages of that method.

For example we can take The training vehicle is arranged like a row of numbers on a number rack. I'm aware that 8 plus 2 equals 10. There are two kids sleeping. Make There are ten facts—pairs of numbers that add up to 10. When adding 30 + 70 = 100 or 43 + 7 = 50, it is helpful to know right away that certain combinations result in 10, such as 3 + 7 = 10.

Hence, The multiples of ten quantity or value of 10 in maths.
