Question

BRAINLIEST FOR THE RIGHT ANSWER What is the value of c?

Answer 1

Okay so you want to use the Pythagorean Theorem, $a^{2} +b^{2} =c^{2}$ in this case it would be: $3^{2} +4^{2} =c^{2}$ . This would come to be 9+16=$c^{2}$. Which leads you to get 25=$c^{2}$. So cancel the square, (find the square root of 25) and you find c=5. Hope this helps !!

Answer 2

check the picture below.

now, what is b?

we can use the same small/medium proportions

$\bf \cfrac{small}{medium}\qquad \qquad \cfrac{5}{b}=\cfrac{3}{4}\implies 20=3b\implies \cfrac{20}{3}=b$
