Answer:
3,4,5
5,12,13
9,12,15
Step-by-step explanation:
Area= 1/2abSinC where a and b are sides and c is an angle. All sides= 6 inches, all angles= 60°
1/2x6x6xSin(60)= 9√3 in2
Answer:
Easiest to pick (0, 0) and (1, 1) probably, then slope is 1.
Step-by-step explanation:
Rise over run for (0, 0) and (1, 1) is rise up 1 and run over 1, so 1/1.
This means slope is 1
