Which trigonometric function has the same value as sin 75?

Sonbull [250]

The answer would be tan (44).

For sin (75)
The answer will be computed this way:
sin 75º = sin (30)º + 45º= sin 30 cos 45+cos 30 sin 45= 1/2*√2/2+√3/2*√2/2=√2/4+√6/4=(√2+√6)/4Check with calculator:sin 75º ≈ 0.9659

For tan (44): checking with the calculator the answer is also: ≈ 0.9659

Jason states that Triangle A B C is congruent to triangle R S T. Kelley states that Triangle A B C is congruent to triangle T S

Brilliant_brown [7]

Answer:

The correct option is;

Jason's statement is correct. RST is the same orientation, shape, and size as ABC

Step-by-step explanation:

Here we have

ABC = (2, 1), (3, 3), (4, 1)

RST = (-4, -2), (-3, 0), (-2, -2)

Therefore the length of the sides are as follows

AB = $\sqrt{(2-3)^2+(1-3)^2} = \sqrt{5}$

AC = $\sqrt{(2-4)^2+(1-1)^2} =2$

BC = $\sqrt{(3-4)^2+(3-1)^2} = \sqrt{5}$

For triangle SRT we have

RS = $\sqrt{(-4-(-3))^2+(-2-0)^2} = \sqrt{5}$

RT = $\sqrt{(-4-(-2))^2+(-2-(-2))^2} = 2$

ST = $\sqrt{(-3-(-2))^2+(0-(-2))^2} = \sqrt{5}$

Therefore their dimensions are equal

However the side with length 2 occurs between (2, 1) and (4, 1) in triangle ABC and between (-4, -2) and (-2, -2) in triangle RST

That is Jason's statement is correct. RST is the same orientation, shape, and size as ABC.

On a workday the average decibel level of a busy street is 69 db, with 139 cars passing a given point every minute. if the numbe

Vlad1618 [11]

Decibel is directly proportional to number of cars passing the point. That is,

69 db ----- 139 cars
x db ----- 17 cars

x = number of cars passing the point per minute on a weekend.

Then,
x= (69*17)/139 = 8.43 db ≈ 8 db

2. A father offers three portions of his crop land to his daughter for a corn maze. All

Tamiku [17]

If the daughter does not want more than 2,250,000 square feet of the corn maze, hence she will choose all the portions

<h3>Circumference and area of circles</h3>

The formula for calculating the area of circle is expressed as;

A = πr²

r is the radius of the circle

If r = 875ft

A = 3.14(875)²

A = 2,404,062.5squar feet

For the diameter = 1715feet

r = 1715/2

A = 3.14(1715/2)²

A =2,308,861.625 square feet

For the third portion has a 5305 feet circumference;

5305 = 2(3.14)r

r = 844.74ft

A = 3.14(844.74)^2

A = 2,240,686.70

If the daughter does not want more than 2,250,000 square feet of the corn maze, hence she will choose all the portions
