<span>Consider the triangles ERT and CTR.
|ER|=|CT| shown
(</span>Therefore, one can say that segment ER is congruent to segment CT.)
m(R)=m(T)= 90°shown
(By the definition of a rectangle, all four angles measure 90°)
|RT|=|TR|
so we have Side Angle Side congruence.
By the <span>(SAS) Theorem, the triangles are congruent.

Answer:
x = ±11/4
Step-by-step explanation:
Rewrite -16x^2+121=0 as 16x^2 - 121=0 and then as 16x^2 = 121.
Take the square root of both sides. This returns 4x = ±11, and so:
x = ±11/4
