The sum is (n-2)180. N is the number of sides. In this case, you have 20 sides. You get (20-2)180, which is 18x180 and results in 3240 degrees. This is the sum!! To get one angle, do the same thing but divide it by 20. The formula, as seen in the question, is (n-2)180/n. Therefore, you have (20-2) 180 divided by the number of signs, which is 20. Since 18 times 180 = 3240 is the (n-2)180, divide 3240 by 20. You get 162° for each angle.

What is tangent of an angle?

The tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side.

According to the given question.

We have a diagram in which we have two right angled triangles.

Now, in the upper right angled triangle

[tex]tan50 = \frac{0pposite side}{5}[/tex]

⇒ 1.19 = 0pposite side/ 5

⇒ opposite side = 1.19 × 5

⇒ opposite side = 1.2 × 5

⇒ opposite side = 6cm

Now, the opposite side w.r.t angle 50  degrees in the upper right angle triangle is a adjacent side w.r.t to angle 38 degrees in the lower right angle triangle.

So, in the lower right angle triangle.

[tex]tan38 = \frac{x}{adjacent side}[/tex]

⇒[tex]0.78 = \frac{x}{6}[/tex]

⇒ x = 0.78 × 6

⇒ x = 4.68

⇒ x = 7cm

Hence, the value of x in the given diagram is 7cm.

Answers

Answer:

25

Step-by-step explanation:

Given,

Measurement of <1 = x + 10

Measurement of <2 = 4x + 5

Also, said in the question that both these angles are complementary.

Therefore, by the problem,

<1 + <2 = 90°

=> x + 10 + 4x + 5 = 90

=> x + 4x + 10 + 5 = 90

=> 5x + 15 = 90

=> 5x = 90 - 15 = 75

[tex] = > x = \frac{75}{5} [/tex]

=> x = 15

Now, we have got the value of x so,

Measurement of <1 is

<1 = x + 10 = 15 + 10 = 25 (Ans)

y is inversely proportional to x.when y=7 x=9 a) work out an equation connecting y and x b) work out the value of y when x=21

Answers

Answer:

a) y = k/x

7 = k/9

b) y = 3

Step-by-step explanation:

From the question, we are told that:

y is inversely proportional to x.

Mathematically:

y ∝ 1/x

y = k × 1/x

y = k/x

k = Constant of Proportionality

a) work out an equation connecting y and x

To find this Equation,

y = k/x

when y=7 x=9

Hence:

7 = k/9

b) work out the value of y when x=21

We find the value of k first

7 = k/9

k = 7 × 9

k = 63

Hence, the value of y when x=21

y = k/x

k = 63, x = 21

y = 63/21

y = 3

A box of chocolates contains milk chocolates and dark chocolates in the ratio 4:3
The box contains 35 chocolates
how many milk chocolates are there in the box?

Answers

Answer:

20 milk chocolates

Step-by-step explanation:

The first step is adding together 4 + 3. You will get 7. This is the total number of units in the box.

Then, divide 35 by 7. You will get 5 as the answer.

To find the number of milk chocolates, multiply 5 and 4. You will get 20 as the answer.

4x+3x=35
7x=35
x=5

milk chocolate 4(5) = 20
dark chocolate 3(5) = 15
