A device used in golf to estimate the distance​ d, in​ yards, to a hole measures the size​ s, in​ inches, that the 7​-ft pin appears to be in a viewfinder. The viewfinder is held 15 inches from the​ viewer's eye. Express the distance d as a function of s.

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc

this is a good question! i’ll do some research and what i find, i’ll contact you asap when i have something! ✊
