Answer:

Proton

Step-by-step explanation:

However, the atom itself is not the smallest known particle, but instead each atom is made up of three individual parts: electrons, protons and neutrons. Furthermore, protons and neutrons themselves are made up of even smaller parts called quarks.

Tresset [83]

4/1 / 5/2 = 4/1 * 2/5 = 8/5

1 7/8 = 15/8

15/8 * 8/5 = 120/40 = 12/4 = 3 inches

shorter side should be 3 inches

Answer:

1.55 feet.

Step-by-step explanation:

From the question given above, the following data were obtained:

Angle R = 24°

Hypothenus = RS = 3.8 feet

Opposite = ST = x

The value of x can be obtained by using the sine ratio. This is illustrated below:

Sine R = Opposite / Hypothenus

Sine 24 = x / 3.8

Cross multiply

x = 3.8 × Sine 24

x = 3.8 × 0.4067

x = 1.55 feet

Thus, the Lenght ST is 1.55 feet.

Answer: b. The adjacent angles formed by two intersecting lines are supplementary.

Step-by-step explanation:

In the given picture , we can see that there are intersecting lines with adjacent angles which have shown.

If we add the adjacent angles for each pair of intersecting lines we get,

$135^{\circ}+45^{\circ}=180^{\circ}$

$130^{\circ}+50^{\circ}=180^{\circ}$

$160^{\circ}+20^{\circ}=180^{\circ}$

Therefore,b is the right option "The adjacent angles formed by two intersecting lines are supplementary."

Two Angles are supplementary when their sum is 180 degrees.

Two Angles are complementary when their sum is 90 degrees.
Vertical angles are always equal.
