Answer:

k = 36

Step-by-step explanation:

By exterior angle theorem:

$k \degree + 110 \degree = 146 \degree \\ \\ k \degree = 146 \degree - 110 \degree \\ \\ k \degree = 36\degree \\ \\ k = 36$

If a 200 N net force acts on a 500 grams car, what will the acceleration of the car be?

ladessa [460]

Answer:

The acceleration of the car will be 400 m/s².

Step-by-step explanation:

The acceleration of the car can be found using Newton second law:

$F = ma$

Where:

F: is the net force = 200 N

m: is the mass = 500 g

a: is the acceleration =?

Then, the acceleration will be:

$a = \frac{F}{m} = \frac{200 N}{500 g*\frac{1 kg}{1000 g}} = 400 m/s^{2}$

Therefore, the acceleration of the car will be 400 m/s².

Please help this is the last problem I need

tangare [24]

Answer:

$sin 54 = \frac{x}{14}$

Step-by-step explanation:

$sine = \frac{opposite}{hypotenuse}$

Side z is the adjacent, since it is next to the angle you are solving for.

Side x is the opposite, since it is opposite the angle you are solving for.

The side measuring 14 is the hypotenuse, since it is across from the right angle.

$sin 54 = \frac{x}{14}$
