Step-by-step explanation:
Pythagorean theorem
Hypotenuse^2 = leg1^2 + leg2^2
30^2 = 23^2 + leg2^2
leg2^2 = 30^2 - 23^2
leg2^2 = 371
leg2 = ~ 19.3 units
Answer:
third side is 19.3
Step-by-step explanation:
a=23,c=30
C²= a²+b²
30²=23²+b²
900=529+b²
900-529=b²
371 = b²
19.26=b
19.3 =b
so the third side is 19.3
