Question

Find the value of c.
a= 1 and b = 4

A.3
B.4.8
C.4.1
D.5.6

Answer 1

√17

Explanation:

a^2 + b^2 = c^2

1 + 16 = 17 = c^2

c = √17

Answer 2

Answer: C

Explanation:

I suppose we are to assume this is a right angle triangle. If that is so then

we need to apply the Pythagorean Theorem..

Pythagorean Theorem: c^2 = a^2 + b^2

a = 1

b = 4

c = ?

c^2 = 1^2 + 4^2 Substitute values for the variables a b c

c^2 = 1 + 16

c^2 = 17 Take the square root of both sides.

√c^2 = √17

c = 4.123
