Answer:

33 and -39

Step-by-step explanation:

Angle on a straight line = 180

|5x + 15| = 180 and |5x + 15| = -180

5x + 15 = 180

Subtract 15 from both sides;

5x = 165

Divide both sides by 5;

x = 33

5x + 15 = -180

Subtract 15 from both sides;

5x = -195

Divide both sides by 5;

x = -39

The sine of angle θ is 0.3. What is cos(θ)?

Sergio [31]

The answer:

$\sqrt{9}1 /10$

Explanation to your question:

Since the sin of theta is 0.3, we can reasonably deduct that the opposite side to theta has a ration of 3 to 10 to that of the hypotenuse. Thus, the adjacent side to theta, using the pythagorean theorem, will be root91. Therefore, since the cosine of theta is the adjacent/hypotenuse, we get root 91/10

Factor (difference of squares) the binomial 25x^2-4 and find one of its factors

Lunna [17]

Step-by-step explanation:

Hey, there!

Here,

Given that:

$= 25 {x}^{2} - 4$

we need to find factor,

As it is in a^2-b^2 form as per its factor (a+b) (a-b), keeping same formula here,

25x^2 means (5x)^2

and 4 means 2^2

Now, it would be,

$= ( {5x)}^{2} - {2}^{2}$

$= (5x + 2)(5x - 2)$

Therefore, it's factor would be (5x+2)(5x-2).

Hope it helps....
