gimana caranya tolong bantu

1.
c = √a² + b²
c = √3² + 4²
c = √9 + 16
c = √25
c = 5

2.
b = √c² - a²
b = √17² - 8²
b = √289 - 64
b = √225
b = 15

3.
a = √c² - b²
a = √20² - 16²
a = √400 - 256
a = √144
a = 12

4.
a = √c² - b²
a = √58² - 42²
a = √3.364 - 1.764
a = √1.600
a = 40

5.
c = √a² + b²
c = √24² + 70²
c = √576 + 4.900
c = √5.476
c = 74

Maaf Kalau Salah
