Answer:
RT=75/4= 18.75
Step-by-step explanation:
RS+ST=RT
x+6+8=5x-5
4x=19
x=19/4
RT=5x-5
RT=5(19/4)-5
RT=95/4-20/4
RT=75/4= 18.75
We'd first convert the mixed fractions to "improper", and proceed, keeping in mind that the volume of a rectangular prism is just length*width*height.
C. as long as two angles are congruent you know that the third angle is congruent as well which by the AAA theorem means the two triangles are similar
