The three interior angles of any triangle add to 180 degress.  Therefore,


180-(120 + 40) = the third angle.


So, 20 is the third angle

Answer: 20°

<u>Step-by-step explanation:</u>

1. B = 120°, C = 40°             1. Given

2. A + B + C = 180°             2. Triangle Sum Theorem

3. A + 120° + 40° = 180°      3. Substitution Property

4. A + 160° = 180°                4. Simplify (added like terms)

5. A = 20°                            5. Subtraction Property of Equality

What net force will make a 5 kg bowling ball accelerate by 1.5 m/s square 2?
s2008m [1.1K]

In pure translation or in roll without slip?

In pure translation, just use Fnet = m*a.  Fnet = 7.5 Newtons

In roll without slip it has effectively more inertia than 5 kilograms.  The effective inertia can be found as:

m_effective = m + I/r^2

For a uniform solid sphere, I = 2/5*m*r^2

So m_effective = 7/5*m

To make a 5 kg bowling ball accelerate at 1.5 m/s^2 in roll without slip, it requires Fnet = 10.5 Newtons, and this ASSUMES that all forces causing the net force on it have lines of action through its center of mass (most common case).

i hope this is what ur looking for

Could anyone please help me find k divided by 9 = 12 as well as 84n = 504 and 6 = m over 148? I need explanations...
Lana71 [14]
<u>k / 9  =  12</u>
Multiply each side of the equation by  9 :    <em>k = 108</em>

<u>84 n = 504</u>
Divide each side of the equation by  84 :      <em>n = 6</em>

<u>6 = m / 148</u>
Multiply each side of the equation by 148 :        <em>888 = m</em>
