D, add all your answers than divide by how many numbers there are
Answer:
6+18=24+16=40 Top one 3+3=6+8=14
Step-by-step explanation:
Easy by adding
the 3rd vertex is on the x axis line which means Y =0
since the longer leg is twice as long as the shorter leg and the length of the shorter leg is a, then twice the length would be 2a ( 2 times a)
so the 3rd vertex is (2a,0)
97 Rounded to the nearest tenth would be 100
