Chose The Missing Side Length And The Trigonometric Ratio You Would Use To Calculate.

Answers

Answer 1

Answer:

The missing value is 2.9mm and cosine was used

Step-by-step explanation:

Given triangle is a right-angled triangle  we can use trigonometric ratios to calculate the missing length.

In the given triangle,

Base = k

Hypotenuse = 15mm

Angle = 79

We will use trigonometric ratio which includes base and hypotenuse.

Using cosine,

[tex]cos\ (angle) = \frac{Base}{hypotenuse}\\cos\ 79 = \frac{k}{15}\\k = cos\ 79 * 15\\k = 0.1908*15\\k = 2.862[/tex]

Rounding off to nearest tenth

[tex]k= 2.9mm[/tex]

Hence,

The missing value is 2.9mm and cosine was used

Find the domain of the relation {(0, 0), (1, 1), (2, 0)). Then determine whether
the relation is a function.

Answers

Answer:

Domain: 0,1,2

The relation is a Function.

Step-by-step explanation:

hope this helps

A relation may or  may not be a function.

The domain of the relation is: [0,2]The relation is a function

The relation is given as:

[tex]\mathbf{(x,y) = \{(0,0),(1,1),(2,0)\}}[/tex]

List out the x-values

[tex]\mathbf{x = \{0,1,2\}}[/tex]

The above set means that the x-values starts from 0 and ends at 2.

Hence, the domain is: [0,2]

For a relation to be a function, all y-values of the relation must point to different x-values.

So, we can say that, the given relation is a function, because all y-values have unique x values

What is Trigonometry?

Trigonometry the area of mathematics that deals with particular angles' functions and how to use those functions in calculations. There are six common trigonometric functions for an angle. Sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant are their respective names and abbreviations.

Given:

sin(80) cos(20°) - cos(80°) sin(20°)

Using Trigonometric identity

sin ( A- B) = sin A cos B - cos A sin B

So, sin(80) cos(20°) - cos(80°) sin(20°)

= sin (80 - 20)

= sin 60

= √3/2

Hence,  sin(80) cos(20°) - cos(80°) sin(20°)= √3/2

We know that f(4)=256. Therefore:

[tex]\displaystyle f(4)=a^4=256[/tex]

A triangle, ABC, has angle measures of 82,75, and 23 and no sides equal (congruent) in length. How would this triangle be classified?

Answers

Answer:

It would be an acute scalene triangle

Step-by-step explanation:

All angles measures are less than 90 so it would be acute. No sides are equal so it would be scalene.

We can classify this triangle as Scalene Acute triangle.

We have a triangle angle measures of 82, 75 and 23 and no sides equal (congruent) in length.

We have to classify this triangle.

What is a Triangle ?

A triangle is a plane figure with three straight sides and three angles.

According to question, we have -

A triangle with no side congruent and all angles acute and unequal.

If all the three sides of a triangle are of same length, then the sides are said to be congruent. In an Equilateral triangle all the sides are congruent. Similarly, a triangle with none of its sides equal or congruent is called a Scalene triangle. An acute angle triangle (or acute-angled triangle) is a triangle in which all the interior angles are acute angles i.e. 0 < [tex]\theta[/tex] < 90. Therefore, it is a Scalene acute triangle.

Hence, we can classify this triangle as Scalene Acute triangle.

A dishonest shopkeeper has two false balances. One balance weighs 10% more while
buying the goods and other weighs 10% less while selling the goods. Find his gain
percent just by weighing,
​

Answers

Answer:

Shopkeepers gain just by weighing is 22.22%

Step-by-step explanation:

Explanation:

Assume that the shopkeeper bought x units of goods i.e. actual weight of goods.

As the balance used to buy goods weighs 10% more, he actually bought x×110100=1.1x weight units i.e. although the shopkeeper paid for x units, he actually bought 1.1x units by weight.

Now he has 1.1x units of goods, but for selling he uses another balance, which actually measures 10% less i.e. 1−0.10=0.9 units for each unit weight of goods sold.

So while selling 1.1x becomes 1.1x0.90=1.2222... units.

Hence, shopkeepers gain just by weighing is 22.22%

Calculate the simple interest on $600 left in account that pays 7% annual interest for 8 years.

Answers

Answer:

S = $336

Step-by-step explanation:

Given the following data;

Principal, P = $600

Rate, R = 7

Time, T = 8 years

To find the simple interest?

Mathematically, it is given by the formula;

Simple interest, S = (P*R*T)/100

Substituting into the equation, we have;

S = (600*7*8)/100

Simplifying the equation, we have;

S = 6*7*8

S = $336
