<em>Answer:</em>
<em>x = 2√5</em>
<em>Step-by-step explanation:</em>
<em>Hi there !</em>
<em>x² = 20</em>
<em>x² = 4×5</em>
<em>x² = 2²×5</em>
<em>x = √2²×5</em>
<em>x = 2√5</em>
<em>Good luck !</em>
Answer:
A.
Step-by-step explanation:
The slope of the line parallel to the original line is the same. And you don't add x after the slope.
70
because the little lines on the lines mean that the bottom two angles are the same
180-40=140
140/2=70
1/3 x 4/4 = 4/12
4/12 + 5/12 = 9/12
12/12 - 9/12 = 3/12
3/12 = 1/4
X^2+y^2=R^2
64+36=R^2
R=10
x^2+y^2=100
