Step-by-step explanation:

I'm not sure if this is correct. I just want to help you and have brainiest

so I used this formula

c²=a²+b²

26²=a²+10²

Explanation:

The left and right walls are mirror copies of one another, and they are also copies of the cross section as well. Think of a subdivision to divide one room into two smaller ones. That middle wall is the same as the left and right walls of the original larger room. Effectively, those two smaller rooms are blocks of their own we can pull apart or cut.

Answer:

Angle ECM is approximately 25.786°

Step-by-step explanation:

The given details are;

The horizontal base of the triangular prism ABCDEF = ABCD

AE = 17 cm = BE

M = The midpoint of AB

AB = 16 cm

BC = 30 cm

In a triangular prism, the angle EBC = 90°

Therefore;

[tex]\overline {CE}^2 = \overline {BE}^2 + \overline {BC}^2[/tex]

[tex]\therefore \overline {CE} = \sqrt{\overline {BE}^2 + \overline {BC}^2}[/tex]

CE = √(17² + 30²) = √1189

Similarly, we have;

[tex]\overline {CM}^2 = \overline {BM}^2 + \overline {BC}^2[/tex]

Where;

BM = AB/2

∴ BM = (16 cm)/2 = 8 cm

Therefore;

CM = √(8² + 30²) = 2·√241

By trigonometric ratio in the triangle formed by the points CEM, which is the right triangle ΔCEM, we have;

cos(∠ECM) = CM/EC

∴ ∠ECM = arccos(CM/EC)

Plugging in the values gives;

∠ECM = arccos((2·√(241)/√(1189)) ≈ 25.786°

Answer:

Answer B is the correct answer..

cot(theta)=cos(theta)/sin(theta)

Trignometric functions are the ratio of the sides of the triangle. The correct option from the following is cot(theta)= cos(theta)/sin(theta).

The trigonometric function gives the ratio of different sides of a right-angle triangle. There are six basic trigonometric functions,

[tex]\rm Sin \theta=\dfrac{Perpendicular}{Hypotenuse}\\\\\\Cos \theta=\dfrac{Base}{Hypotenuse}\\\\\\Tan \theta= \dfrac{Sin \theta}{Cos \theta} =\dfrac{Perpendicular}{Base} \\\\\\Cosec \theta=\dfrac{1}{Sin\theta}=\dfrac{Hypotenuse}{Perpendicular}\\\\\\Sec \theta= \dfrac{1}{Cos\theta} = \dfrac{Hypotenuse}{Base}\\\\\\Cot \theta=\dfrac{1}{Tan\theta}= \dfrac{Base}{Perpendicular}\\\\\\[/tex]

where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite to the 90° angle.

As we know about the basic trigonometric functions, therefore, the options that is correct from the following option is cot(theta)= cos(theta)/sin(theta).

Answer:

Step-by-step explanation:

take 30 degree as reference angle

using sin rule

sin 30=opposite/hypotenuse

1/2=x/10(do cross multiplication)

2*x=10*1

x=10/2

x=5

Answer:

5

Step-by-step explanation:

The sin is the opposite cathetus divided by the hypothenuse, and the sin30° = 0.5, so let's do an equality:

sin30° = x/10

0.5 = x/10

10•0.5 = x

x = 5

there will be about 115 customer

Step-by-step explanation:

the y intercept is 2.5

(0,2.5)  (100 ,35)

the slope is (y2-y1)/(x2-x1)

m = (35-2.5)/(100-0)

m= (32.5)/100

m = .325

y = mx+b

y = .325x+2.5

let y =40  for 40 cars in all the spot

40 = .325 x + 2.5

subtract 2.5

37.5 =.325 x

divide by .325

37.5 /.325 = x

First choice

Step-by-step explanation:

The discontinuity is removable if by reducing the fraction that discontinuity doesn't continue to exist as a discontinuity.

Example of, (x-1)/(x-1) has a a discontinuity at x=1 and it's removable because the fraction reduces to 1 which doesn't have a discontinuity at x=1.

Example not of, (x-1)/(x-2) has a discontinuity at x=2 and it is not removable because we can't get rid of the x-2 factor in the denominator.

The first choice has a discontinuity at x=-1 and it is removable because x^2-x-2=(x-2)(x+1) and the x+1's will cancel on top and bottom making the point at x=-1 a removable discontinuity.

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = S(12, 9) and (x₂, y₂ ) = T(21, 3)

[tex]m_{ST}[/tex] = [tex]\frac{3-9}{21-12}[/tex] = [tex]\frac{-6}{9}[/tex] = - [tex]\frac{2}{3}[/tex]
