The measure of the angle formed by 2 chords that intersect inside the circle is 1/2 the sum of the chords' intercepted arcs.
m∠RST = (143+33)/2 = 176/2 = 88°
Answer:
another way to write this is 1:3
Answer:
Solution given:
<R=<J=49°[ inscribed angle standing on a same Aaka equal in a circle]
<K=90°[inscribed is triangle on a semicircle is 90°]
now in triangle JKL
<J+<K+<L=180°[ sum of interior angles of a triangle is 180°]
49°+90°+<L=180°
<L=180°-49°-90°=41°
:.arcJK=41°
is your answer.
Angle LHC is equivalent to angle NHU because they are vertical angles.
Vertical angles must be equal because they share the same vertex (center point).
You could say it as Vertical Opposite Angles because it means the <u>exact same thing</u>.
Hope this helps :)
I have one question what is interior angle but the answer is 45
