Given sin theta=5/13 and cos theta=12/13, which of the following can be proven using a Pythagorean identity?

ZanzabumX [31]

Answer:

4th option

Step-by-step explanation:

given

sinΘ = $\frac{5}{13}$ and cosΘ = $\frac{12}{13}$ , then

( $\frac{5}{13}$ )² + ( $\frac{12}{13}$ )²

= $\frac{25}{169}$ + $\frac{144}{169}$

= $\frac{25+144}{169}$

= $\frac{169}{169}$

= 1

showing sin²Θ + cos²Θ = 1

X/2−5=−12<br> I need to know how to get the answer to what X is

QveST [7]

Answer:

-14

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

x/2-5=-12

1/2x+-5=-12

1/2x-5=-12

Step 2: Add 5 to both sides.

1/2x-5+5=-12+5

1/2x=-7

Step 3: Multiply both sides by 2.

2*(1/2x)=(2)*(-7)

x=-14

8.76× 10 6 is times than 8.76× 10 2 .

VashaNatasha [74]

10^6 = 10 *10*10*10*10*10 = 1,000,000

10^2 = 10*10 = 100

1000000/100 = 10,000 times larger
