Answer:
QT = RT
Step-by-step explanation:
When drawing triangle PQR the perpendicular bisector cuts the triangle in half, which results in two sides that are congruent. This makes QT and RT congruent.
S^2 + s^2 = 9^2 => 2s^2 = 81 => s^2 = 81/2 => side length s = 9(sqrt(2))/2 = 6.37 cm.
Answer:
x=4
Step-by-step explanation:
-2(x+2)=-12
x+2=-12/-2
x+2=6
x=6-2
x=4
Answer:
1 6/15
Step-by-step explanation:
15/15-9/15=6/15
30 = 6 x 5
6 = 3 x 2
8 = 4 x 2
4 x 2 + 3 x 2 + 6 x 5 = 44
