Please answer it right Chelsea drew two parallel lines, KL and MN, intersected by a transversal PQ, as shown

below:

Which fact would help Chelsea prove that the measure of angle KRP is equal to the

measure of angle MSR?

A. When angles KRS and MSR are equal to angle RSN, the angles KRP and MSR are congruent.

B. When angles KRP and KRS are equal to angle LRS, the angles KRP and MSR are congruent.

C. When angle LRS is equal to angle KRP and angles LRS and RSN are complementary, angle KRP and angle MS are congruent.

D. When angle LRS is equal to both the angles KRP and MSR, angle KRP and angle MSR are congruent to each other.

for ex: the reciprocal of 3/4 is 4/3. it is the opposite.

reciprocal definition:

a mathematical expression or function so related to another that their product is one; the quantity obtained by dividing the number one by a given quantity.

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).

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
