Well,you can use the pythagorean theorem,which is a^2+b^2=c^2 to solve for x.

$x+31$ and $2x-59$ are congruent sides

So we have
$2x-59=x+31$
⇒ $x-59=31$
⇒ $x=90$

Plug in:
$x+31=90+31=121$
$2x-59=2(90)-59=180-59=121$
$x-7=90-7=83$

In right triangle ABC, angle C = 90 degrees, c = 3, and a + b = square root of 17. Compute the area of the triangle.

Klio2033 [76]

Answer:

2

Step-by-step explanation:

Given in the question,

a + b = √17

(a+b)² = 17

a² + b² +2ab = 17

a² + b² = 17 - 2ab

<h3>Area of triangle </h3>

1/2 (h)(b)

here h is perpendicular height of triangle = a

b is the base of triangle = b

<h3>Use pythagorus theorem:</h3>

hypotenuse² = base² + height²

3² = a² + b²

9 = a² + b²

9 = 17 - 2ab

9 - 17 = -2ab

-8 = -2ab

cancel minus on both sides

8 = 2ab

ab = 8/2

ab = 4

Plug ab in the formula of area

1/2 (h)(b)

1/2 (a)(b)

1/2 (4)

4/2

Answer: Second Option

$m=0.09$

Step-by-step explanation:

The formula for calculating the average rate of change between two values of x ( $x_1$ and $x_2$ ) is:

$m=\frac{f(x_2)-f(x_1)}{x_2-x_1}$

$f (x_1)$ and $f (x_2)$ are the values of the function when $x = x_1$ and $x = x_2$

In this case

$x_1=3\\x_2=6$

Observe that when $x=3$ , $f(x) =2.41$ and when $x=6$ , $f(x)=2.68$

Finally the average rate of change from 3 to 6 storms is:

$m=\frac{2.68-2.41}{6-3}$

$m=0.09$
