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 = 
5x>/ 45
at least means it can be 45 and up
So it becomes greater than or equal to
Answer:
3-i
Step-by-step explanation:
1-5i + 2 +4i
We add the real parts
1+2 =3
We add the imaginary parts
-5i + 4i = -1i
The complex number is
3-i
Answer:
x = -14
Step-by-step explanation:
4x + 8 = 3x - 6
4x = 3x - 14
x = -14
