Complementary angles

Step-by-step explanation:

Complementary angles are when two angles add up to 90 degrees.

3x + 10 + 47 = 90

3x + 10 = 43

3x = 33

x = 11

Answer:

D. 14°

Step-by-step explanation:

The Law of Sines tells you sides are in proportion to the sine of the opposite angle:

sin(A)/BC = sin(B)/AC

sin(A) = BC/AC·sin(B)

A = arcsin(BC/AC·sin(B)) = arcsin(7/28·sin(75°)) ≈ 13.974° ≈ 14°

stiks02 [169]

Answer:

Every decade, the number of species decays by a factor of 0.0834.

Step-by-step explanation:

Let be $S(t) = 25,000,000\cdot 0.78^{t}$ , $\forall t \geq 0$ . The decay rate per decay is deducted from the following relation:

$\frac{S(t+10)}{S(t)} = \frac{25,000,000\cdot 0.78^{t+10}}{25,000,000\cdot 0.78^{t}}$

$\frac{S(t+10)}{S(t)} = 0.78^{t+10-t}$

$\frac{S(t+10)}{S(t)} = 0.78^{10}$

$\frac{S(t+10)}{S(t)} = 0.0834$

Every decade, the number of species decays by a factor of 0.0834.
