Find the volume of a trough 5 meters long whose ends are equilateral triangles, each of whose
yawa3891 [41]

Answer:

V=5\sqrt{3}\ m^3

Step-by-step explanation:

we know that

The volume of a trough is equal to

V=BL

where

B is the area of equilateral triangle

L is the length of a trough

step 1

Find the area of  equilateral triangle B

The area of a equilateral triangle applying the law of sines is equal to

B=\frac{1}{2} b^{2} sin(60\°)

where

b=2\ m

sin(60\°)=\frac{\sqrt{3}}{2}

substitute

B=\frac{1}{2}(2)^{2} (\frac{\sqrt{3}}{2})

B=\sqrt{3}\ m^{2}

step 2

Find the volume of a trough

V=BL

we have

B=\sqrt{3}\ m^{2}

L=5\ m

substitute

V=(\sqrt{3})(5)

V=5\sqrt{3}\ m^3

Helppppp meeee plzzzzz
andrew-mc [135]

Answer:

∠B = 41°

Step-by-step explanation:

∠BCD is an exterior angle of the triangle

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠A and ∠ B are the 2 opposite interior angles, hence

∠A + ∠B = 113, that is

72 + ∠B = 113 ( subtract 72 from both sides )

∠B = 41°

A figure undergoes a rigid motion, such as a rotation. If the figure has line symmetry, does the image of the figure have line s
vesna_86 [32]

Answer:

The answer is yes most shapes do have line of symmetry for such task. The ones that don't would be irregular shapes or small changes to its handle on more obscure symmetrical shapes, ie) they do not fit in itself due to a handle being rotated before hand, so things that appear to be symmetrical can have a symmetrical line even if they do not fit in their selves at say anything under 360 rotation.

Find the area of this isosceles trapezoid. A) 85.5 units2 B) 171 units2 C) 342 units? 345 units?​
liubo4ka [24]

9514 1404 393

Answer:

  B) 171 units^2

Step-by-step explanation:

The area is given by the formula ...

  A = 1/2(b1 +b2)h

Filling in the given base and height values, we find the area to be ...

  A = 1/2(23 +15)(9) = (19)(9) = 171 . . . square units

_____

<em>Additional comment</em>

You can select the correct answer choice simply on the basis of "reasonableness." If this were a 9×15 rectangle, its area would be 9×15 = 135 square units, more than 85.5. You know its area is less than a 9×23 rectangle, so is less than 9×23 = 207 square units. Only one answer choice is a value between 135 and 207.

__

Multiplication by 9 is not so hard. It is multiplication by 10-1:

  15×9 = 15×(10 -1) = 150 -15 = 135
