If two chords intersect inside a circle, the acute angle they form is one half of the sum of the arcs intercepted by its sides and by the vertical angle SO... The acute angle will be one half the sum of the two arcs. So it is 1/2(42+94)=68 degrees.
Sometimes
Yes and the angles around the point of intersection add up to 360 degrees.
It is 90 degrees between the circle's diameter and its tangent
The geometric figure formed when two planes intersect is called a polygon.* * * * *Wrong!The correct answer is a straight line.
Two pairs of adjacent angles are formed when two lines intersect each other.
Not unless the chords are both diameters.
yes
yes
Sometimes
False
Yes and the angles around the point of intersection add up to 360 degrees.
100 degrees
15pi. after you add.
Assuming the measure of the arc refers to the angle at the centre of the circle, the answer is 180 - 150 = 30 degrees.
The angle between the two tangents is 20 degrees.
it the circumference of a circle
