Question

PLEASE HELP AND ACTUALLY HELP!

Answer 1

Answer:

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

Answer 2

Answer:

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
