Answer:
The answer is 20
Step-by-step explanation:
Given that f(2)=1/5
And f(n+1)=f(n)*10
Let's start from n=2
f(2+1)=f(2)*10
f(3)=(1/5)*10
f(3)=2
Now let's take n=3
f(3+1)=f(3)*10
f(4)=2*10
f(4)=20
Answer:
The answers are A, C, and D
Answer:
90 or 85
Step-by-step explanation:
it is a right angle, and all the sides must add up to 180 degrees so yes, 85, im pretty sure.
67+52+x=180
119+x=180
x=61
hope this helps!
the equation to be used would be x=180-(67+52)
