PLEASE HELP AND ACTUALLY HELP!

c = 5 cm

Step-by-step explanation:

Use Pythagorean Theorem

3^2 + 4^2 = x^2

9 + 16 = x^2

25 = x^2

x = 5

The Pythagorean theorem is a^2+b^2=c^2

Only usable for right triangles

A is leg

B is another leg

Whilst c is the Hypotenuse    

We’re trying to find c here so we can subsitute here

3 and 4 are both legs so if we plug them both into the theorem

3^2 + 4^2 = c^2

9 + 16 = c^2

25= c^2

√25 = c^2

c= 5

the answer to the question is a

step-by-step explanation:

it has the same slope and the same y-intercept.

y + 11 = -7/9(x - 18)

y + 11 =-7/9x + 14

b

y = -7/9x + 3

y-intercept (0, 3)
