Answer:
x≈17.5
Step-by-step explanation:
a^2 + b^2 = c^2 (In this case, c is x.)
Subsitute.
9^2 + 15^2 = c^2
Solve.
81 + 225 = c^2
306 = c^2
Square both sides.
√306 = √c^2
17.4928556845 = c
Round to nearest tenth.
17.5 = c
Answer:
17.5 units
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem which states that a^2+b^2=c^2
Plug in what we know....
9^2+15^2=c^2
81+225=c^2
c=sqrt(306)
c=17.5
