What is the value of x in the triangle
KonstantinChe [14]

Answer:

x = 17

Step-by-step explanation:

This is a right triangle so we can use the Pythagorean theorem

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

15^2 + x^2 = (sqrt(514))^2

225 + x^2 = 514

Subtract 225 from each side

225-225 + x^2 = 514-225

x^2 =289

Take the square root of each side

sqrt(x^2) = sqrt(289)

x = 17

What is the slope and why?
N76 [4]

Answer:

Step-by-step explanation:

ok slope is m because there is a thing called y-intercept, so you use x to find slope.

the whole formula is y = mx +b

in this case m = slope with x being the part of the slope from where you got it from

the answer would be m = \frac{1}{2}x

i hope this helped :)
