Answer:

A

Step-by-step explanation:

Answer:

[tex]84mm^{2} [/tex]

I think this is true

Answer = 84

BECAUSE

 8x6/2 for triangles (24)

 x2 bc two triangles (48)

6x6 for square (36)

add it all = (84)

Answer:

[tex]The~triangles~AED~and~ABC~are~similar.\\So,\\\frac{AD}{AB} = \frac{DE}{BC} [Corresponding~sides~of~similar~triangles~are~proportional.]\\or, \frac{30}{15} = \frac{34}{x} \\or, x = \frac{15(34)}{30} = 17inches[/tex]

Answer:

360°

Step-by-step explanation:

Based on what I know that the total of degrees has to be 360°. So, two sides of the rhombus have to have two acute angles and two obtuse angles. So, the  Image shows that the 63° is an acute angle. So, multiply 63 by 2 which is 126. Then subtract 126 from 360 which is 234. Then, divide 234 by 2 which is 117. Lastly, add 63 with 63 and 117 with 117 which is 360.

Hopefully, you understand.

Answer:

c = 14.9 cm

Step-by-step explanation:

Applying the Law of Sines, we would have the following:

c/sin(C) = b/sin(B)

c = ??

C = 180 - (150 + 12) = 18°

b = 10 cm

B = 12°

c/sin(18) = 10/sin(12)

Multiply both sides by sin(18)

c = (10*sin(18))/sin(12)

c = 14.9 cm (nearest tenth)

Answer:

Step-by-step explanation:

The possible trigonometric function is option (C) [tex]sec \theta = \frac{3}{\sqrt{5} }[/tex] and [tex]tan \theta = \frac{-2}{\sqrt{5} }[/tex] is the correct answer.

Trigonometry is mainly concerned with specific functions of angles and their application to calculations. Trigonometry deals with the study of the relationship between the sides of a triangle (right-angled triangle) and its angles.

For the given situation,

The trigonometric function, sin θ = -2/3

We know that [tex]sin \theta = \frac{opposite}{hypotenuse}[/tex]

So, opposite = -2, hypotenuse = 3

The other side of the right triangle adjacent side can be found by using the Pythagoras theorem,

[tex]adjacent=\sqrt{hypotenuse^{2} -opposite^{2} }[/tex]

⇒ [tex]adjacent=\sqrt{3^{2} -(-2)^{2} }[/tex]

⇒ [tex]adjacent=\sqrt{9-4 }[/tex]

⇒ [tex]adjacent=\sqrt{5}[/tex]

Now, [tex]cos \theta = \frac{adjacent}{hypotenuse}[/tex] and [tex]tan \theta = \frac{opposite}{adjacent}[/tex]

Then, [tex]cos \theta = \frac{\sqrt{5} }{3}[/tex]

[tex]sec \theta = \frac{1}{cos \theta}[/tex]

⇒ [tex]sec \theta = \frac{1}{\frac{\sqrt{5} }{3} }[/tex]

⇒ [tex]sec \theta = \frac{3}{\sqrt{5} }[/tex]

[tex]tan \theta = \frac{-2}{\sqrt{5} }[/tex]

Hence we can conclude that the possible trigonometric function is option (C) [tex]sec \theta = \frac{3}{\sqrt{5} }[/tex] and [tex]tan \theta = \frac{-2}{\sqrt{5} }[/tex] is the correct answer.

Answer:

a. 138 + x = 180

Step-by-step explanation:

Because the angles given are 69+69

which equal 138

and x being the missing angle

finally the total of all angles in a triangle = 180

Answer:

17 hours is the total of miles he walked

Answer:

Step-by-step explanation:

rn = 6 miles in 2 hrs

we want 9 hours

Per hour it will be 3 miles

3 miles = 1 hr

6 miles = 2 hrs

9 miles = 3 hrs

12 miles = 4 hrs

15 miles = 5 hrs

18 miles = 6 hrs

21 miles = 7 hrs

24 miles = 8 hrs

27 miles = 9 hrs

All you basically had to do is multiply the 9 hours with 3 since that's how much you get per mile, and then you get your total of 27 miles

Answer:

The answer is "717.25 minutes".

Step-by-step explanation:

In this question first, we arrange the value in ascending order that are:

307,311,321,322,354,363,377,406,425,435,461,464,474,499,505,513,517,534,548

The median is always in an orderly position that is [tex]= \frac{(n+1)}{2}[/tex].

[tex]\to \frac{(n+1)}{2} = \frac{(20+1)}{2} = 10.5[/tex]  position orders

[tex]10^{th} \ and \ 11^{th}[/tex] place an average of observations so, the

[tex]Average = \frac{(425 +435)}{2} = \frac{(860)}{2} =430[/tex]

Because as medium stands at 10.5 that median is as below 10 are greater than the level.

[tex]Q_1[/tex] often falls throughout the ordered BELOW average is [tex]= \frac{(n+1)}{2}[/tex] place.

[tex]\to \frac{(n+1)}{2} = \frac{(10+1)}{2} = 5.5^{th}[/tex]ordered position

Average [tex]5^{th} \ and \ 6^{th}[/tex]  location findings

[tex]Q_1 = \frac{(354+363)}{2} = \frac{(717)}{2}= 358.5[/tex]

In  [tex]= \frac{(n+1)}{2}[/tex] the ordered place, Q3 always falls ABOVE the median.

[tex]\to \frac{(n+1)}{2} = \frac{(10+1)}{2} = 5.5^{th}[/tex] ordered At median ABOVE 

Consequently [tex]Q_3[/tex] falls between [tex]5^{th} \ and \ 6^{th}[/tex] ABOVE the median position

[tex]15^{th}\ and \ 16^{th}[/tex]place average of observations

[tex]\to Q_3 = \frac{(499+505)}{2}=\frac{(1004)}{2} = 502[/tex]

[tex]\to IQR = Q_3 - Q_1= 502-358.5= 143.5[/tex]  

[tex]\to \text{Upper fence} = Q_3 + 1.5 \times IQR= 502 + 1.5 \times 143.5 = 717.25[/tex]

Shape P is translated to shape Q using vector [tex]\left[\begin{array}{ccc}2\\4\end{array}\right][/tex].

"A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other."

Given, the shape P is mentioned on the graph.

Now, shape P is translated to shape Q.

Therefore, in order to reach Q from P, the shape needs to shift to the left 2.

After that the shape needs to shift downwards 4 places.

Therefore, the required vector is [tex]\left[\begin{array}{ccc}2\\4\end{array}\right][/tex].
