3.29 + 1 = 4.29
4.29 x 3 = 12.87
Answer:
A
Step-by-step explanation:
Answer:
a/b=1/(x-y)
Step-by-step explanation:
cause ax^2-bx=ay^2+by
so ax^2-ay^2=bx+by
a(x^2-y^2)=b(x+y)
a(x+y)(x-y)=b(x+y)
a(x-y)=b
so a/b=1/(x-y)
Answer:
x= 36
Step-by-step explanation:
both angles together are supplementary and will form 180
Therefore, you know the missing angle can be found by substracting 108 from 180
180 - 108 = 72
72 = 2x
