Asecant and a tangent to a circle intersect in a 42-degree angle. the two arcs of the circle intercepted by the secant and the tangent have measures in a 7: 3 ratio. find the measure of the third arc

The measure of the third arc is

Step-by-step  explanation:

step 1

we know that

The measurement of the external angle is the semi-difference of the arcs which comprises

in this problem

Let

x----> the greater arc of the circle intercepted by the secant and the tangent

y----> the smaller arc of the circle intercepted by the secant and the tangent

----> equation A

-----> equation B

Substitute equation B in equation A and solve for y

Find the value of x

step 2

Find the measure of the third arc

Let

z------> the measure of the third arc

we know that

-----> complete circle

substitute the values and solve for z

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

answer: it's upside down and i can't read it
