tolong jawab ya..... No 1. yg a, b, d, e terus yg no 3 yg a sm b, jangan lupa penjelasan nya y, ini tentang rumus phytagoras

1. a) x²= 15²+12²
= 225+144
=√369
x= 19.2

b) x²= 13²-5²
=169-25
=√144
x=12

d) a²=10.4-9.6
=108.16-92.16
=√16
a=4

e) x²=8²-6²
=64-36
=28
x=5.2

3. a) c²= a²-b²
= 20²-12²
= 400-144
=√256
c=16

b)1. b²= a²-c²
=13²-5²
=169-25
b²=√144
b=12

2. a²=b²+c²
=12²+35²
=144+1225
=√1369
a=37
