In the same circle, or in congruent circles, two chords are congruent if and only if they are equidistant<span> from the center. States that the measure of an inscribed angle is one half the measure of its intercepted arc. States that if two inscribed angles of a circle intercept the same arc, then the angles are congruent.
Hope this helps</span>
Answer:
X=1/2
Step-by-step explanation:
-2x1/2=-1
-2x1=-2
-1+-2=-3
1) move the 10 over to the other side which would give you 28.
2) divide by 4 to get x by itself.
ANSWER: 7
Answer:
4x² - 28xy + 49y²
Step-by-step explanation:
(2x - 7y)²
= (2x - 7yy)(2x - 7y)
Each term in the second factor is multiplied by each term in the first factor, that is
2x(2x - 7y) - 7y(2x - 7y) ← distribute parenthesis
= 4x² - 14xy - 14xy + 49y² ← collect like terms
= 4x² - 28xy + 49y²
