Answer:
23.3
Step-by-step explanation:
Use phyth. Thm.
a^2 + b^2 = c^2
A and B are the side lengths, and C is the hypotenuse. The hypotenuse is across the right angle.
Since you only have one side length and the hypotenuse this what your equation will look like:
30^2 + x^2 = 38^2
900 + x^ = 1444
544 = x^2
x = roughly 23.3
The equation would be:
x≥-4
7s + 20 = 4s -13
7s - 4s = -13 -20
3s = -33
s = -33/3
s = -11
