Answer:

Step-by-step explanation:
<u>Similar Triangles</u>
Lines ST and QR are parallel. Thus, angles S and Q are congruent, and angles T and R are congruent.
Considering the triangle PQR, the sum of its internal angles must be 180°:

Substituting the known values:

Solving for R:


Angles S and Q are congruent, thus

Angles T and R are congruent, thus

Summarizing:

Answer:
(10x squared -4) - (7x squared +3)
X^2 + 3x - 4 = 6
x^2 + 3x - 10 = 0 (Now reverse FOIL)
(x + 5)(x - 2)(Now x will equal the opposites of your numbers)
x = -5
x = 2
