Cuantos triangulos distintos pueden construirse con un angulo de 15 grados , un lado que mida 10 y otro ,7 cm, si ese angulo no esta entre ellos
Answers
Answer:
La cantidad de triángulos diferentes que se pueden construir son 3 triángulos
Step-by-step explanation:
El número de triángulos que se pueden construir usando la información de Ángulo lateral dado como 'a', 'b' y ,A son;
Dónde;
a = 10 cm
b = 7 cm
A = 15 °
Dónde;
∠A = El ángulo entre el lado de 10 cm y el lado desconocido
Tenemos;
a> b · sin∠A
10> 7 × pecado (15 °),
Por tanto, tenemos un posible triángulo
Cuando a = 7 cm y b = 10 cm, ∠A = 15 °, tenemos;
7 <10
10 × pecado (15 °) ≈ 2,59 cm
∴ 7> 2.59 Por lo tanto, hay dos triángulos soluciones
Sea 'B' el ángulo adyacente al lado de 10 cm y el lado desconocido, por lo tanto, tenemos;
7 × sin (15 °) = 10 × sin (B)
B = arcosen (7 × sin (15 °) / 10) ≈ 10,44 °
Por lo tanto, el número total de triángulos posibles es 2 + 1 = 3 triángulos

You want to order some books that cost $16 each. Shipping is $8 per order.
If you buy 12 books, what will the order cost?
$192
$112
$288
$200
Answers
Answer:
$200
Step-by-step explanation:
12 x 16 = 192
192 + 8 = $200
$16 a book and you’re getting 12 so 12 multiplied by 16 = 192 plus shipping ($8 per order and this is only one order so only add 8 once.)

wants to make 24 quarts
of this mixture , how many quarts of
each color does she need?
Answers
Answer:
5 quarts yellow + 2 quarts orange + 1 quart white = 8 total quarts.
To make 24 quarts you need 3 times as much, because 8 * 3 = 24.
Multiply each measurement by 3:
5 quarts yellow --> 15 quarts yellow
2 quarts orange --> 6 quarts orange
1 quart white --> 3 quarts white

Write an expression that is equivalent

Answers
Answer: 5/8b + 4/5
EXPLAIN: It's too easy explain it yourself. (LOL)
The value of the equation is A = ( 5/8 )b + 4/5
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
A = ( 2/8 )b + ( 3/8 )b + ( 4/5 ) be equation (1)
On simplifying the equation , we get
A = [ ( 2/8 )b + ( 3/8 )b ] + 4/5
A = ( 5/8 )b + ( 4/5 )
On further simplification , we get
A = ( 25b + 32 ) / 40
Therefore , the value of A is ( 5/8 )b + ( 4/5 )
Hence , the equation is A = ( 5/8 )b + ( 4/5 )

Each edge of the cube measures 4 inches in length
What is the distance, in inches, from vertex B to vertex H? Round your answer to the nearest tenth of an inch
Answers
Answer: The distance from vertex B to vertex H is 6.9 inches.
Step-by-step explanation:
The length of the line BH can be thought of as the hypotenuse of a triangle rectangle where the catheti are the lines HD (whit a measure of 4in) and line DB.
The length of the line DB can be thought of as the hypotenuse of a triangle rectangle where the catheti are lines DA and AB (both are 4in long)
Then if we use the Pythagorean's theorem, the length of line DB is:
(DB)^2 = (DA)^2 + (AB)^2
(DB)^2 = (4in)^2 + (4in)^2 = 32in^2
(DB) = √(32in^2) = 5.66 in
Whit this, we can find the length of line HB as:
(HB)^2 = (HD)^2 + (DB)^2
(HB)^2 = (4in)^2 + (DB)^2 = 16in^2 + 32in^2 = 48in^2
HB = √(48in^2) = 6.93 in
If we round to the nearest thent, we get:
HB = 6.9 in
The distance from vertex B to vertex H is 6.9 inches.

a pig on a farm loses 14 pounds when it sick. then it gains 8 pounds. the total weight can be represented by the number?
Answers
Answer:
If the pig loses 14 pounds, then gains eight pounds, then the answer would basically be how much the pig weighed before it got sick, minus 6.
Step-by-step explanation:
This question is basically subtraction. Since the weight of the pig before it got sick is not stated, I'm going to use the letter n as the number the pig weighed before it got sick. If it loses 14 pounds then gained eight pounds, that would be n - 14 + 8. which basically means n - 6.
Hope this helps.

Answer:
Option 1 y = 210 - 7x
Step-by-step explanation:
Since she will be buying "x" amount of books she will lose money because she has to pay for them. Each book costs $7 so if she buys "x" books she will lose 7x dollars. Therefore the right equation would be...

What is trigonometric identity?Trigonometric Identities are equality statements that hold true for all values of the variables in the equation and that use trigonometry functions. There are numerous distinctive trigonometric identities that relate to a triangle's side length and angle.
It is given that in the right-angle triangle ABC the three sides are AB = 4.24, BC = 3 and AC = 3.
The value of cosine is the ratio of the base of the right-angle triangle and the hypotenuse of the right-angle triangle.
The value of cosA is calculated as below:-
cosA = 4.24 / 3
The value of cosB is calculated as below:-
cosB = 4.24 / 3
Calculating the ratio of cosA and cosB.
cosA / cosB = [ 4.24 / 3 ] ÷ [ 4.24 / 3 ]
