A triangle with an area of 37 units? is dilated by a scale factor of . Find the area of

sergeinik [125]

Answer:

58 units

Step-by-step explanation:

I decided that one side is 37 units and another is 2 units, since that would make the area 37 units. (you can also use 74 units and 1 unit)

Then I multiplied 37 by 5/4, which equals a new length of 46.25 units, and I also multiplied 2 by 5/4, which equals a new length of 2.5 units.

Finally, I solve for the area of the triangle:

1/2(46.25 x 2.5) ≈ 58 units (rounded to the nearest whole number)

A trapezoid has an area of 30m^2. if all of its side lengths are tripled, what will its new area be

Norma-Jean [14]

Answer:

270

Step-by-step explanation:

Because we do not know what the side lengths are, as long as they multiply to 30m^2, it's fine

For this question, let's just say the base is 5, and the height is 6. If we triple 5, we get 15, and if we triple 6, we get 18. 15*18=270

Now what if, the sides are not 5 and 6. Will the area still be the same? Let's find out.

10*3=30 so we can say for this answer, the base is 3, and the height is 10.

10 tripled is 30, and 3 tripled is 9. 30*9=270

So as we look at these 2 answers. we can conclude that the new area, no matter the side lengths, will be 270

Hope this helpes!

20 points helppppppppppppppppppppppppppppp PLZZ anyone solve this ASAP

Sonja [21]

Answer:

$cos^{-1}(cos\frac{ 7π}{6})=cos^{-1}(cos\frac{7*180}{6})$

$cos^{-1}(cos{210})$

$cos^{-}(cos(180+30))$

[since in third quadrant cos 30=- $\frac{\sqrt{3}}{2}]$

$cos^{-}(- \frac{\sqrt{3}}{2})$

:150°or $\frac{5π}{6}$

150°or  $\frac{5π}{6}$ is a required answer.
