Answer:
x=50
Step-by-step explanation:
since its an isosceles triangle, both of the base angles are going to be the same. Since all of a triangle's angles combined equal 180, and you already have one angle, subtract the 80 from 180.
this leaves you with 100. since there are two angles left, divide 100 by two and thats the value of x
hope this helps!! :)

Answer:
r = 3sqrt*2
Step-by-step explanation:
We'll need the formula for the circumference of a circle: C = 2*pi*r
This can be solved for r:
C
r = -----------
2*pi
Here, with C = 6sqrt(2)*pi,
6sqrt(2)*pi
r = ------------------ = 3sqrt*2
2*pi
Diego multiplied the bases together and also added the powers together, you cannot do that unless the bases are the same and 6 and 8 are not the same.
