Use the diagram to complete the statement. Triangle J K L is shown. Angle K J L is a right angle. Angle J K L is 52 degrees and
zzz [600]

Answer:

\bold{sin(38^\circ)=cos(52^\circ)}

Step-by-step explanation:

Given that \triangle KJL is a right angled triangle.

\angle JKL = 52^\circ\\\angle KLJ = 38^\circ

and

\angle KJL = 90^\circ

Kindly refer to the attached image of \triangle KJL in which all the given angles are shown.

To find:

sin(38°) = ?

a) cos(38°)

b) cos(52°)

c) tan(38°)

d) tan(52°)

Solution:

Let us use the trigonometric identities in the given \triangle KJL.

We have to find the value of sin(38°).

We know that sine trigonometric identity is given as:

sin\theta =\dfrac{Perpendicular}{Hypotenuse}

sin(\angle JLK) = \dfrac{JK}{KL}\\OR\\sin(38^\circ) = \dfrac{JK}{KL}....... (1)

Now, let us find out the values of trigonometric functions given in options one by one:

cos\theta =\dfrac{Base}{Hypotenuse}

cos(\angle JLK) = \dfrac{JL}{KL}\\OR\\cos(38^\circ) = \dfrac{JL}{KL}....... (2)

By (1) and (2):

sin(38°) \neq cos(38°).

cos(\angle JKL) = \dfrac{JK}{KL}\\OR\\cos(52^\circ) = \dfrac{JK}{KL} ...... (3)

Comparing equations (1) and (3):

we get the both are same.

\therefore \bold{sin(38^\circ)=cos(52^\circ)}

Area of Composed Figures - Quiz-Level G

The number of square feet of the carpet is the area of the carpet

The number of square feet of outdoor carpet is 32 feet

<h3>How to determine the number of square feet</h3>

To do this, we simply divide the carpet to regular shapes.

The outdoor carpet can be divided to the following shapes from top to bottom

  • Rectangle of 4 ft by 2 ft
  • Rectangle of 6 ft by 2 ft
  • Rectangle of 6 ft by 2 ft

So, the area of the outdoor carpet is:

Area = 4 * 2 + 6 * 2 + 6 * 2

This gives

Area = 32

Hence, the number of square feet of outdoor carpet is 32 feet

What is the equation of the line that passes through the point (3,2) and has a slope of 2/3 ​
Sladkaya [172]

Answer:

y= ⅔x +1

Step-by-step explanation:

(3,2) = (x_1,y_1) \\  m =  \frac{2}{3}

Substitute values into point slope form

y -y_1 = m(x - x_1) \\ y - 2 =  \frac{2}{3} (x - 3) \\ y - 2 =  \frac{2}{3} x - 1 \\

y =  \frac{2}{3} x - 1 + 2 \\ y =  \frac{2}{3} x + 1
