Order the angles of from largest to smallest if:

RS = 14 RT = 12 ST = 11

• $\angle T\ <\ \angle S\ <\ \angle R$

• $\angle T\ >\ \angle S\ >\ \angle R$

• $\angle R\ >\ \angle S\ >\ \angle T$

• $\angle S\ <\ \angle T\ <\angle R$

The measures of the angles of triangle ΔABC are  $m\angle A=\left(4x+10\right)\degree$  ,  $m\angle B=\left(2x\right)\degree$   , and  $m\angle C=50\degree$  . 

Order the sides from smallest to largest.   

• BC, AB, AC

• AC, AB, BC
