Can any one help me on this? this is on my math test due at 11:59.

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

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

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
