Answer:
x = ± 2
Step-by-step explanation:
Given
x² = 20 ( take the square root of both sides )
x = ± 
= ± 
= ± 2
<span>Since RT bisects QS, we have QT congruent to ST. Bisect means it cuts QS in half. The we have RT congruent to RT since it is the same. By SSS, we have triangle QRT congruent to triangle SRT since QT is congruent to ST, RT is congruent to RT, and QR is congruent to SR. Each side is congruent to its respective side in the other triangle and that is SSS (side, side, side).</span>

Answer:
A≈254 cm^2
Step-by-step explanation:
The area of a circle is given by formula: π
r^2
π has a constant value of 3.14 And the radius of the circle is 9
c
m
the area= π
r^2 = 3.14 x (9)^2 cm^2
