Right angle=90°.
(X-20) + X = 90.
Then solve for X.
X=55
<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: </span><span>C (SAS) Theorem</span>
Answer:
31x³-60x²+7x-75
Step-by-step explanation:
(30x³-49x³+7x)+(50x³-60x²-75)
(-19x³+7x)+(50x³-60x²-75)
-19x³+50x³+7x-60x²-75
31x³-60x²+7x-75
If this is a true or false question, than this is true.
