How do I solve for what is sin A for the triangle shown

PtichkaEL [24]

Option a:

sin A for the triangle is $\frac{3}{5}$ .

Solution:

The given triangle is a right triangle.

The adjacent side to angle A is AC.

The opposite side to angle A is BC.

Hypotenuse is AB.

AC = 8, BC = 6 and AB = 10.

Using trigonometric ratio formulas,

$$\sin \theta=\frac{\text { Opposite side }}{\text { Hypotenuse }}$

$$\sin A=\frac{BC}{AB}$

$$\sin A=\frac{6}{10}$

Divide both numerator and denominator by 2, we get

$$\sin A=\frac{6\div2}{10\div 2}$

$$\sin A=\frac{3}{5}$

Hence sin A for the triangle is $\frac{3}{5}$ .

Option a is the correct answer.

How many time larger is 9x10^-8 than 3x10^-12

kkurt [141]

Step-by-step explanation:

$\frac{9 \times 10 {}^{ - 8} }{3 \times 10 {}^{ - 12} }$

Apply Quoteint of Powers. Divide the intergers. serpately.

Note that Quotient of Powers is

$\frac{a {}^{x} }{a {}^{y} } = a {}^{x - y}$

So the answer is

$3 \times 10 {}^{ - 8 + 12} = 3 \times 10 {}^{4}$

The answer is

$3 \times 10 {}^{4}$

$30000$
