Hey there!
I don't know if it's too late, but oh well: The answer is 108°
Knowing that supplementary angles add up to 180°, and we also know that we have 2 out of 3 of the angle measures, so we can subtract that from 180:
180 - 72 =108°
Have a terrificly amazing day!
16) -40
17) -2
18) -5
19) -10
That’s all.
Step-by-step explanation:
2x + 5x(5x-7) = 100
2x+ 25x-35x=100
2x -10x =100
-8x =100
x=2/25
The answer is B. Hope you get it.
Answer:
The conjecture is that the unit digit of 4^n = 4 when n = odd also 4^n = 6 when n = even
Step-by-step explanation:

The conjecture is that the unit digit of 4^n = 4 when n = odd also 4^n = 6 when n = even
To prove this conjecture
unit digit = 6
hence the property is true for ; n = 1 and n = 2 and also for every odd and even number ( i.e. from 1 to 8 )
