Answer:

x = 19.5 ( to the nearest tenth )

Step-by-step explanation:

Since the triangle is right, we can use the cosine ratio to find x

cos46° = $\frac{adjacent}{hypotenuse}$ = $\frac{x}{28}$

multiply both sides by 28

x = 28 × cos46° = 19.450 ≈ 19.5

Answer:

Step-by-step explanation:

When you have a straight line with a transversal, the two angles are equal to 180 degrees

180=123+3x ---> subtract 123 to the other side

57=3x ---> divide by 3

x=57/3

x=19

The sum of the base and height of a triangle is 14 cm. Which of the following equations could be used to find the maximum area o

Montano1993 [528]

Answer:

Step-by-step explanation:

Let the base of the triangle be b and the height be h.

The sum of the base and height is 14. Thus:

$b+h=14$

Recall that the area of a triangle is given by:

$\displaystyle A=\frac{1}{2}bh$

From the first equation, solve for either variable:

$h=14-b$

Substitute:

$\displaystyle A=\frac{1}{2}b(14-b)$

Distribute:

$\displaystyle A=\frac{1}{2}(14b-b^2)$

Distribute:

$\displaystyle A=-0.5b^2+7b$

Let b = x. Hence:

$A=-0.5x^2+7x$

Therefore, our answer is B.
