Answer:


Step-by-step explanation:
The ∆ given is an isosceles ∆ with a right angle measuring 90°, and two congruent angles measuring 45° each.
Using trigonometric ratio formula, we can find the lengths of the missing side as shown below:
Finding e:


hyp = 26
opp = e = ?
Plug in the values into the formula

Multiply both sides by 26





Since side e is of the same length with side f, therefore, the length of side f =
