Answer:
60 degrees
Step-by-step explanation:
sum of interior angles in a triangle is always 180 degrees
find m<E from triangle CED: 43 + m<E + 35 = 180 degrees
m<E = 102 degrees
find m<A: 102 + m<A + 18 = 180
m<A = 60 degrees
Answer:17g/mole or 1.67*10^18g/mole
Step-by-step explanation:
Easy
450=3000*3*r
R=450/9000
R=0.05*100
R=5%
Answer:
it is similar- this ~ squiggly thing means similar
Step-by-step explanation:
the scale is 3 so x=3.8*3 which is <u>11.4</u>

Step-by-step explanation:

height of ball (a) = 10m
fraction of height decreases by each bounce (r) = 2/3
