add 4 and 5i to both sides to get x on its own:
collect like terms. This is the other number.
Answer:
A=9in,b =9in
Step-by-step explanation:
This is a right angled triangle
Formula = a2×b2=c2 (ie sq of both adj sides equals the sq of the longest side)
So, a2 × b2 = c2
But both sides are equal, so we can as well say 2(a2) = (9|2)^2
2a^2 = 162
Divide through by 2
A^2 = 81
So, a = |81
A = 9
And since both sides are equal, a = b = 9
