Reason:

2. SD ⊥ HT. ∴ ∠SDH = ∠SDT =90°

3. Given (It is given in the question)

5. RHS congruence

(Here, the right angle, hypotenuse and one side of ΔSHD is congruent to that of ΔSTD).

Statement:

4. Line segment SD = SD

(Reflexive property is used to prove congruence of triangles. This property is used when an angle or line segment is congruent to itself.)

Answer:

(x + 5)(x + 10) = 0

Step-by-step explanation:

When you solve for the equation: $\frac{1}{x-4}-\frac{14}{x+2}+1=0$ , you get that the answer is $x=10,\:x=5$ .

Hope this helped!!
