For Triangle ABC, use the Pythagorean Theorem to find the missing length for the given measures. Round each length to the nearest tenth.
b=9, c=18, a= _____
.
Pythagorean theorem:
a^2 + b^2 = c^2
where
c is the hypotenuse (side opposite the 90 degree angle)
a and b are the other two sides
.
Assuming, then, that 'c' is the hypotenuse, we have:
a^2 + b^2 = c^2
a^2 + 9^2 = 18^2
a^2 + 81 = 324
a^2 = 324 - 81
a^2 = 243
a =
a = 15.6
