Answer
c=1.7
Work Step by Step
The legs are 0.8 and 1.5. You have to find the hypotenuse so you plug in a and b into the Pythagorean theorem $a^{2}$ + $b^{2}$= $c^{2}$ --> $0.8^{2}$ + $1.5^{2}$= $c^{2}$:
$0.8^{2}$ + $1.5^{2}$= $c^{2}$ -simplify the exponents-
0.64+2.25 = $c^{2}$ -add the like terms-
2.89= $c^{2}$ - find the square root of 2.89 to solve for c-
$\sqrt 2.89$=1.7
c=1.7
C is 1.7
