Answer:

Solution given:

Sin\theta_{1}=\frac{-24}{25}

\frac{opposite}{hypotenuse}=\frac{-24}{25}

equating corresponding value

opposite=-24

hypoyenuse=25

adjacent=x

By using Pythagoras law

hypotenuse²=opposite²+adjacent²

25²=(-24)²+x²

625=576+x²

x²=625-576

x=49

x=\sqrt{49}=7

In IV quadrant

Cos angle is positive

Cos\theta_{1}=\frac{adjacent}{hypotenuse}

<h3>Cos\theta_{1}=\frac{7}{25}</h3>

Answer:

cos theta = 7/25

Step-by-step explanation:

sin theta = opp / hyp

We can find the adj side by using the pythagorean theorem

adj ^2 + opp ^2 = hyp^2

adj^2 + (-24)^2 = 25^2

adj^2 +576 = 625

adj^2 =625 -576

adj^2 = 49

Taking the square root of each side

adj = 7

Since we are in the 4th quadrant, adj is positive

cos theta = adj / hyp

cos theta = 7/25

How do I find the absolute value
pychu [463]

Absolute value of function = - 9 / 3 .

The absolute value or modulus of a real number x, denoted by |x|, is the non-negative value of x without regard to its sign. Namely, |x|=x if x is a positive number, and |x|=-x if x is negative (in which case negating x makes -x positive) , and |0|=0.

For example, the absolute value of 3 is 3, and the absolute value of −3 is also 3. The absolute value of a number may be thought of as its distance from zero.

x ≥ 1.52 / 3 x - 1 = 2 / 3 x + 4⇒ -1 = 4 which is not possible .Now for all x ≤ 1.5- 2 /3 x + 1 = 2 / 3 x + 4⇒ 4 / 3 x = -3  x = - 9 /4 Hence absolute value = - 9 / 3 .

This is about angles. Please answer someone?
NISA [10]
Actually, this is not about angles.  It's about the length of the sides in a right triangle.

In EVERY right triangle, the squares of the lengths of the short sides add up
to the square of the length of the longest side.  You're in high school math,so
I'm SURE you've heard that in class before ... possibly even just before you
were assigned this problem.

Let's say that again:  The squares of the lengths of the sides that meet at
the  right angle add up to the square of the length of the longest side.  In
the triangle in this particular problem, that means
                                                                             a² + b² = c²

You know the lengths of 'b' and 'c', so you shouldn't have any trouble finding
the length of 'a'.
