What type of angle is formed when the radius and a tangent intersect at the points of tangency?

a. right
b. straight
c. obtuse
d. reflex

ANSWER

A. Right

EXPLANATION

A tangent to a circle touches the circle at only one point.

The point where a tangent and a radius meet at is called the point of tangency.

The tangent to a circle meets the radius of a circle at a right angle.

This is because the angle between the tangent and the radius of the circle is 90°

The correct answer is A.

answer: 1, 3 and 5 are correct

step-by-step explanation:

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
