[tex] \cos( \beta ) = \frac{5}{13} = 0.385[/tex]
Cos (B) in the right angled triangle is 5/13 .
Given,
Right angled triangle .
Now,
In right angled triangle
Perpendicular = 12
Base = 5
Hypotenuse = 13
So,
According to trigonometric functions,
CosФ = base / hypotenuse
sinФ = perpendicular / hypotenuse
tanФ = perpendicular / base
So,
Substitute the value in the function of cos,
Cos(B) = base / hypotenuse
Cos(B) = 5 / 13
Thus the value of function cos (B) is 5/13 .

Write an equation to find the missing length of Alex's room. Let x = missing length in feet
Solve to find the missing length of Alex's room
Answers
Answer:
the missing length is 14 feet.
Step-by-step explanation:
a = L × W
168ft² = 12 × W - divide both sides of the equation by 12
- 168 ÷ 12 = 14
168ft² = 12 × 14

Francois is paid $52 per day for a job that lasts 4 days. He is paid $67 per day for a different job. Francois earned a total of $610. How many days was he paid $67 per day?
Answers
Answer:
6 days
Step-by-step explanation:
$52 per day for 4 days: 4 * $52 = $208
Total pay: $610
Pay for remaining days: $610 - $208 = $402
Number of $67/day days: $402/($67/day) = 6 days
Answer: 6 days
The perimeter of a rectangular area is 16ft.
Write an expression for the sum of the length and width.
Answers
Answer:
Length + Width = 8 ft
Step-by-step explanation:
"The perimeter of a rectangle is 16 ft."
A perimeter is the sum of four sides of a rectangle.
OR...
Perimeter = Side 1 + Side 2 + Side 3 + Side 4
A rectangle has "matching sides", so...
Length: Side 1 = Side 3
Width: Side 2 = Side 4
Therefore we can just say that:
Perimeter = (Length * 2) + (Width * 2)
We can pull the 2 out:
Perimeter = 2 * (Length + Width)
Since Perimeter = 18
16 = 2 * (Length + Width)
Divide both sides by 2
8 = Length + Width
Length + Width = 8 ft

The length (JL) of the right-angle triangle will be 1.732 units.
What is a right-angle triangle?It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.
In the right triangle shown, angle ∠K = 60° and KL is 2. Then the measure of the length JL will be given by the sine the angle ∠K. Then the equation is given as,
JL / KL = sin ∠K
h / 2 = sin 60°
h / 2 = √3 / 2
h = √3
h = 1.732 units
The length (JL) of the right-angle triangle will be 1.732 units.

complete the statement of each of these rules:
a (+)×(?)=(+)
b (-)×(+)=?
c (?)×(-)=?
Answers
Answer:
a) (+) × (?) = (+)
(?) = (+)
b) (-) × (+) = ?
? = (-)
c) (?) × (-) = ?
? is undefined
Step-by-step explanation:
a) (+) × (?) = (+)
From the given equation in the question, by dividing both side of the equation by (+), we have;
((+) × (?))/(+) = (+)/(+)
(?) = (+)/(+) = (+)
Therefore, we have;
(+) × (+) = (+)
(?) = (+)
b) (-) × (+) = ?
From the given equation in the question we apply the operation rules as follows;
(-) × (-) = (+)
(-) × (+) = (-)
Therefore;
(-) × (+) = ? = (-)
? = (-)
c) (?) × (-) = ?
From the rules of multiplication, we have;
(-) × (-) = (+)
(+) × (-) = (-)
Therefore, when (?) = (-), ? = +, from which we have;
(?) ≠ ?, which is an error
Similarly, when (?) = (+), ? = -, therefore, (?) and ?, always changes sign
Therefore, the equation, (?) × (-) = ?, is undefined.

Step-by-step explanation:
Linear pairs are supplementary. Vertical angles are congruent. An angle is the sum of its parts.
(a) C: supplementary to 138°, 180° -138° = 42°
(b) O: congruent to 138°
(c) R: supplementary to 32°, 180°-32° = 148°
(d) H: congruent to 32°
(e) S: complementary to 28°, 90° -28° = 62°
(f) O: supplementary to 122°, 180° -122° = 58°
(g) W: congruent to 122°
(h) C: supplementary to 28°, 180° -28° = 152°
(i) I: supplementary to 60°, 180° -60° = 120°
(∠TSW) E: supplementary to a right angle: 180° -90° = 90°
(∠TSU) O: half the complement of 20°, (90° -20°)/2 = 35°
(∠USW) H: complement of ∠TSU, 90° -35° = 55°
(∠RSV) A: supplement of ∠VSW = 180° -35° = 145°

The desired order of the letters corresponds to the sequence of angles ...
122°, 55°, 58°, 35°, 62°, 120°, 90°, 148°, 71°, 152°, 138°, 145°, 42°, 32°
