Quadrilateral abcd ? is inscribed in a circle. what is the measure of angle a? enter your answer in the box. m? a= ° a quadrilateral inscribed in a circle. the vertices of quadrilateral lie on the edge of the circle and are labeled as a, b, c, d. the interior angle a is labeled as left parenthesis 4 x plus 5 right parenthesis degrees. the angle c is labeled as left parenthesis x plus 15 right parenthesis degrees.

step-by-step explanation:

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
