Question

find x⁴+y⁴ if x+y=7 and xy=10​

Answer 1

Step-by-step explanation:

As per diagram l∣∣m and n transversal.

We know that vertically opposite angles are equal

a=110

o

----(1)

d=85

o

----(2)

We also know that corresponding angles are equal.

a=b

d=c

=>a=b=110

o

[ from (1)]

=>d=c=85

o

[ from (2)]
