Answer:

α ≈ 76°

Step-by-step explanation:

The vertices of a rectangle are right , that is 90°

Using the tangent ratio in right triangle ABC

tanα = $\frac{opposite}{adjacent}$ = $\frac{BC}{AB}$ = $\frac{12}{3}$ = 4, then

α = $tan^{-1}$ (4) ≈ 76° ( to the nearest degree )

Consider the following sequence of numbers.

Leto [7]

Answer:

Blank 1 is -3

Blank 2 is 183

Step-by-step explanation:

Let r be common ratio

$r = \frac{ - 9}{3} \\ r = - 3$

Sum of first 5 terms

$s = \frac{a( {r}^{n} - 1)}{r - 1} \\ s = \frac{ 3( {( - 3)}^{5} - 1) }{ - 3 - 1} \\ s = 183$

The mass of Saturn is approximately 6 × 10^26 kg, while the mass of Mercury is approximately 3 × 10^23 kg. Which of the followin

yanalaym [24]

The right answer is:

C. The mass of Saturn is approximately two thousand times the mass of Mercury.

Step-by-step explanation:

We will find the ratio of both masses to compare them.

Given

Mass of Saturn = S = $6*10^{26}\ kg$

Mass of Mercury = M = $3 * 10^{23}\ kg$

The ratio of larger mass to smaller is:

$\frac{S}{M} = \frac{6*10^{26}}{3*10^{23}}\\= \frac{6*1000*10^{23}}{3*10^{23}}\\= 2*1000\\=2000\ times$

Hence,

The right answer is:

C. The mass of Saturn is approximately two thousand times the mass of Mercury.
