Answer:

  103°

Step-by-step explanation:

The law of sines tells you ...

  sin(C)/c = sin(A)/a

  sin(C) = (c/a)sin(A)

  C = arcsin(c/a·sin(A)) = arcsin(37/19·sin(30°)) ≈ 180° -76.8° ≈ 103°

Obtuse angle C is about 103°.

Step-by-step explanation:

Using the box and whisker plot, it is found that the percent of those in the survey get at least 90 milligrams of Vitamin C is of:

A. between 25% and 50%.

A box and whisker plot shows three things:

In this problem, we have that: P25 = 80, P50 = 85, P75 = 95.

Hence, 90 is between the median and the 75th percentile, which means that between 25% and 50% of those in the survey get at least 90 milligrams of Vitamin C, and option A is correct.

Answer:

5√(7)m  or 13.23m

Step-by-step explanation:

use pythagorean theorem

a²+b²=c²

c=20

b=15

a²+225=400

a²=175

√(175) = 5√(7) = 13.23

The height of the kite is 13.23 meters.

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem.

Given:

A boy is flying a kite.

The length of the string is 20 meters and the horizontal distance between the boy and the kite is 15 meters.

Assuming there is no slack in the string,

then the height of the kite is,

= √(20)² - (15)²

= 13.23 feet.

Therefore, the height is 13.23 meters.

Answer: (0,4)

Step-by-step explanation:

The complex number z = 4 into its rectangular form

Every complex number may be represented in the form a + bi, where a and b are real numbers. A complex number is an element of a number system that extends the real numbers with a specific element labeled I sometimes known as the imaginary unit, and satisfying the equation i² = 1.

Given

* Lets revise the complex numbers

- If z = r(cos Ф ± i sin Ф), where r cos Ф is the real part and i r sin Ф is the imaginary part in the polar form

- The value of i = √(-1) ⇒ imaginary number

- Then z = a + bi , where a is the real part and bi is the imaginary part

 in the rectangular form

∴ a = r cos Ф and b = r sin Ф

* Lets solve the problem

∵ z = r (cos Ф ± i sin Ф)

∵ z = 4 (cos π/2 + i sin π/2)

∴ The real part is 4 cos π/2

∴ The imaginary part is 4 sin π/2

- Lets find the values of cos π/2 and sin π/2

∵ The angle of measure π is on the positive part of x axis at the

 point (0 , 4)

∵ x = cos π/2 and y = sin π/2

∴ cos π/2 = 0

∴ sin π/2 = 1

∴ a = 4(0) = 0

∴ b = 4(1) = 4

∴ z = 0 + i (4)

* The complex number z = (0,4) into its rectangular form
