Answer:
a.2^(a+b+c)
b.2^(a+b+a-b)=2^(2a)or 4^a
c.2^(a+b+c)/2^(a+b)=2^(a+b+c-a-b)=2^c
1. Angle-Side-Angle (ASA) Postulate.
2. corresponding parts of congruent triangles are congruent (CPCTC).
Answer:
c
Step-by-step explanation:
t(a+2)= 3+a+2/a+2-3= 5+a/a-1
Answer:
107
Step-by-step explanation:
the angle left of the 57 is 180-57 = 123
Sum of angles in quadilateral is 360, so
x = 360 - 60 - 70 - 123 = 107
