Answer:

Cos;

26 degrees

Step-by-step explanation:

Recall: SOH CAH TOA

Reference angle = y°

Adjacent side = 18 in.

Hypotenuse = 20 in.

We would apply the trigonometric function CAH since we are dealing with the Adjacent side (A) and the Hypotenuse (H). Thus:

Cos y° = Adj/Hyp

Cos y° = 18/20

Cos y° = 0.9

y° = cos^{-1}(0.9)

y = 25.8419328° ≈ 26 degrees (nearest whole degree)

The answers are:

Cos and 26 degrees

What is the product?<br> (38b* )-822

sergey [27]

Answer:

$\boxed{\sf D)\:-24a^3b^7}$

Step-by-step explanation:

$\sf (3a^2b^4)(-8ab^3)$

We'll use rule of exponents to simplify expression.

$\sf 3^1a^2b^4(-8)^1a^1b^3$

Now, use the commutative property of multiplication.

$\sf 3^1(-8)^1a^2a^2b^4b^4$

In order to multiply power of the same base, we add their exponents.

$\sf 3^2(-8)^1a^{2+1}b^{4+3}$

→ Add exponents:

$\sf 3^1(-8)^1a^3b^7$

→ Multiply 3* -8

$\sf -24a^3b^7$

Tell me how you got the it

stich3 [128]

Answer:

x° = 67°

Step-by-step explanation:

1. The first three diagrams are showing you that opposite exterior angles are congruent. Based on that, when you are faced with opposite exterior angles in the fourth diagram, you are able to conclude they are congruent. That means x° = 67°.

2. You can determine the other angles in the figure based on linear angles being supplementary, and same-side interior angles being supplementary. After you work through all the angles, you find that x = 67.

What’s the Value for k?

xeze [42]

Answer:

Step-by-step explanation:

The sum of the angles on a straight line is 180 degrees. Therefore,

Angle XYZ + angle MYZ = 180

Angle XYZ + 115 = 180

Angle XYZ = 180 - 115 = 65 degrees

The sum of the angles in a triangle is 180 degrees. It means that

Angle XZY + angle YXZ + angle MYZ = 180

Therefore,

4k + 5 + 6k + 10 + 65 = 180

4k + 6k + 5 + 10 + 65 = 180

10k + 80 = 180

10k = 180 - 80 = 100

Dividing the left hand side and the right hand side of the equation by 10, it becomes

10k/10 = 100/10

k = 10
