Find the measure of each angle.

The inside angles of a triangle equal 180 degrees
so
(2x -2) + (x+6) + x = 180
combine like terms
4x + 4 = 180
subtract 4 from both sides
4x = 176
divide both sides by 4
x = 44

Now, wherever is says x, plug in 44
(x+6)
44 + 6
angle B is 50

2x - 2
2(44) -2
88-2
Angle A is 86

and the last angle is just 44

To check:
angle a + angle b + angle c =?= 180
86 + 50 + 44 =?= 180
180 = 180

Hope this helps

A ladybugs length measures 2cm express this measurement in meters explain your thinking include an equation with an exponent in

Ksivusya [100]

All we really need to do here is to convert 2 cm to meters. There are 100 cm in 1 meter, so the appropriate cm to meters conversion factor is

1 meter
-----------
100 cm

Thus,

2 cm 1 m
-------- * ----------- = (1/50) m = 0.02 m or 2.0*10^(-2) m (answer)
1 100 cm

Use the differential equation given by dy/dx=xy/3, y>0 complete the table of values

melisa1 [442]

The $\dfrac{\mathrm dy}{\mathrm dx}$ row is filled by just plugging in the corresponding values of $x$ and $y$ into the ODE.

For example, when $x=-1$ and $y=1$ , you have

$\dfrac{\mathrm dy}{\mathrm dx}=\dfrac{xy}3\implies\dfrac{\mathrm dy}{\mathrm dx}\bigg|_{x=-1,y=1}=\dfrac{(-1)(1)}3=-\dfrac13$

and so on.
