Answer:

a right angle is 90 degrees with a corner thats an L. An acute angle is less than 90 degrees such as 45,60,65, 74, etc. an obutuse triangle had angles that are three diffrent ones one angle should be more than 90 degrees (ex. 130, 25,25)

In triangle ABC, cos A =

nikitadnepr [17]

The other expression that has a value of $\frac{7}{25}$ is A) sin B.

Step-by-step explanation:

Step 1:

$sin\theta = \frac{oppositeside}{hypotenuse} ,$ $cos\theta = \frac{adjacentside}{hypotenuse} ,$ $tan \theta = \frac{opposite side}{adjacent side} .$

For angle B, the opposite side measures 7 units, the adjacent side measures 24 units and the hypotenuse measures 25 units.

$sinB= \frac{oppositeside}{hypotenuse} = \frac{7}{25} ,$ $tan B = \frac{opposite side}{adjacent side} = \frac{7}{24} ,$ $cosB = \frac{adjacentside}{hypotenuse} = \frac{24}{25}.$

Step 2:

For angle A, the opposite side measures 24 units, the adjacent side measures 7 units and the hypotenuse measures 25 units.

$tan A = \frac{opposite side}{adjacent side} = \frac{24}{25} .$

Step 3:

tan C cannot be determined as C is the right angle. The opposite side and hypotenuse of the triangle would be the same.

So sin B also has a value of $\frac{7}{25}.$ This is option A.

Por término de temporada varias tiendas liquidan pantalones. Su precio de temporada era de $6. 990. Si quiero comprar tres panta

nlexa [21]

La tienda que ofrezca la mejor oferta por tres pantalones será aquella que tenga el mayor descuento de liquidación posible.

<h3>Análisis contextual de una pregunta incompleta</h3>

En este problema no es posible determinar cuántas tiendas existen ni los descuentos de liquidación ( $x$ ) correspondientes a cada uno y que todas las tiendas venden los pantalones al mismo precio de temporada ( $C$ ).

Las condiciones <em>matemáticas</em> de cada variable es:

$C = 6990$ (1)

$x \in$ $[0, 1)$ (2)

$n = 3$ (3)

La fórmula matemática para el precio final ( $C'$ ), en pesos, es la siguiente:

$C' = 3\cdot (6990)\cdot (1-x)$ (4)

Consideremos el caso de $N$ tiendas, cada una con un descuento de liquidación por cada pantalón y que ese descuento es aplicable a la compra de tres pantalones, entonces la tienda que ofrezca la mejor oferta por tres pantalones será aquella que tenga el mayor descuento de liquidación posible. $\blacksquare$
