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 = 
3t-2+t=4-7t
4t-2=4-7t
-6=-11t
6/11=t
The answer would be 5.79

24.9/150* 100%= 16.6%
16.6% of 150 is equal to 24.9~
