Answer:

7.6 ft² ( to 1 dec. place )

Step-by-step explanation:

given 2 sides of a triangle and the angle between them, the area (A) is calculated using the formula

A = \frac{1}{2}ac sin B

   = 0.5 × 4 × 13 × sin 17° ≈ 7.6

Solve the equation.<br> -2(4 + 3x) = 3(x - 2)
anygoal [31]

Answer:

-2\9

OR

-0.2

Step-by-step explanation:

−2(4+3x)=3(x−2)

Use the distributive property to multiply −2 by 4+3x.

-

−8−6x=3(x−2)

Use the distributive property to multiply 3 by x−2.

-

−8−6x=3x−6

Subtract 3x from both sides.

−8−6x−3x=−6

-

Combine −6x and −3x to get −9x.

−8−9x=−6

Add 8 to both sides.

−9x=−6+8

-

Add −6 and 8 to get 2.

−9x=2

Divide both sides by −9.

x = 2\-9

Fraction 2\-9  can be rewritten as -2\9 by extracting the negative sign.

SO..

ANSWER IS = -2\9

What is the length of the hypotenuse of the triangle when x=14
astra-53 [7]

The length of the hypotenuse will be equal to H=122.25 when value of x=14.

<h3>What is pythagorean theorem?</h3>

Pythagorean theorem states that in the right angle triangle the hypotenuse square is equal the square of the sum of the other two sides.

It is given that:

Value of x=14

The perpendicular is  =6x+5=6x14+5=89

The base is  =6x=84

So by using the Pythagorean theorem:-

H^2=P^2+B^2\\\\\\H^2=89^2+84^2\\\\\\H=\sqrt{89^2+84^2}\\\\\

Hence the value of hypotenuse will be H=122.25

To know more about the Pythagorean theorem follow
