A building is 60ft high. From a distance at point A on the ground, the angle of elevation to the top of the build is 40 degrees. From a little closer at Point B, the angle of elevation is 70 degrees. Find the distance from point A to point B. (Please give explanation too, as in how you found the answer)

Given: lines a and b are parallel and line c is a transversal. prove: 2 is supplementary to 8 what is the missing reason in the proof? statement reason 1. a || b, is a transv 1. given 2. ∠6 ≅ ∠2 2. ? 3. m∠6 = m∠2 3. def. of congruent 4. ∠6 is supp. to ∠8 4. def. of linear pair 5. ∠2 is supp. to ∠8 5. congruent supplements theorem corresponding angles theorem alternate interior angles theorem vertical angles theorem alternate exterior angles theorem

I'm a polygon i have no parallel lines i am formed 3 line segments i have one right angle two of my angles are angles what am i

Use the irregular polygon below. show all work. a. find the perimeter. b. find the area. the angles of the irregular polygon is 2, 8, 8, and 4.
