A triangle has one angle that is three times the size of another, and a third angle that is 16degrees smaller than the larger of

Dafna11 [192]

Answer:

26, 68 and 84

Step-by-step explanation:

Let the angle that is three times smaller than another be X.

Since the angle sum of a triangle is 180 degrees, we can form the following equation:

X + 3X + (3X- 16) = 180

Now we can simplify this equation:

7X - 16 = 180

7X = 196 (add 16 to both sides)

X = 196/7

X = 28

Therefore, the smallest angle is 28 degrees.

And from here we can figure out the other angles as they are 3x28 and 3x28 - 16.

So the three angles are 28 degrees, (3x28-16) 68 degrees, and (3x28) 84 degrees.

Assuming that $3u + 12v\neq0$, simplify $\dfrac{12u^3 + 48u^2v}{3u+12v}$.

Kay [80]

Answer:

4u²

Step-by-step explanation:

$\dfrac{12u^3 + 48u^2v}{3u+12v}=\dfrac{12u^2(u+4v)}{3(u+4v)}=\boxed{4u^2}$

Common factors cancel from numerator and denominator. The one factor that might make the expression undefined is given as non-zero, so no additional restrictions apply.

Explain weather or not the two triangles below could lie on the same line. Be sure to use the slope of each triangle in your jus

KonstantinChe [14]

Answer:

No, these triangles cannot lie on the same line.

Step-by-step explanation:

For two triangles to lie on the same line they must have the same slope.

The slope of the bigger triangle is

$m=\frac{rise}{run} =-\frac{18}{10} =-1.8$

and the slope of the smaller triangle is

$m=\frac{rise}{run} =-\frac{2}{3} =-0.67$

slopes are negative because the triangles are leaning to the left.

We see that the slopes of the two triangles are not the same; therefore, they cannot lie on the same line.
