Answer:
Step-by-step explanation:
Solution
Here,
h²=p²+b²
or,15²=x²+7²
or,225=x²+49
or,x²=225-49
or,x²=176
x=13.266

Answer:
z = 6/13
Step-by-step explanation:
The new value of x is 13/3 times the old value. Since z is inversely proportional to x, it will be multiplied by the inverse of that, 3/13.
2 × 3/13 = 6/13 . . . . value of z when x=13
