Answer and Step-by-step explanation:

Simply use the Pythagorean Theorem to solve.

The Pythagorean Theorem is used to solve for a side in right triangles.

$A^{2} +B^{2}= C^{2}$

<u>Plug the sides values into the equation.</u>

$A^{2} + 13^2 = 20^2\\\\A^2 + 169 = 400\\\\A^2 = 231\\\\A = 15.1987$ <- This is the answer.

Find an equation of the line that has the given slope and contains the given point. m=7/3 (1,6)

iris [78.8K]

The point-slope form:

$y-y_1=m(x-x_1)$

We have the point (1, 6) and the slope m = 7/3. Substitute:

$y-6=\dfrac{7}{3}(x-1)$ <em>use distributive property</em>

$y-6=\dfrac{7}{3}x-\dfrac{7}{3}$ <em>add 6 to both sides</em>

$y=\dfrac{7}{3}x+\dfrac{11}{3}$ <em>multiply both sides by 3</em>

$3y=7x+11$ <em>subtract 7x from both sides</em>

$-7x+3y=11$ <em>change the signs</em>

$7x-3y=-11$

Answer:

point-slope form: $y-6=\dfrac{7}{3}(x-1)$

slope-intercept form: $y=\dfrac{7}{3}x+\dfrac{11}{3}$

standard form: $7x-3y=-11$
