As shown below, an observer (o) is located 400 feet from a building (b). the observer notices a kite (k) flying at a 29° angle of elevation from his line of sight. what equation and trigonometric function can be used to solve for the height (h) of the kite? what is the height of the kite? you must show all work and calculations to receive full credit.

(a right triangle is shown with one leg measuring 400 and another leg measuring h. one angle is marked 29 degrees.)

Nina has prepared the following two-column proof below. she is given that ∠oln ≅ ∠lno and she is trying to prove that ol ≅ on. triangle oln, where angle oln is congruent to angle lno step statement reason 1 ∠oln ≅ ∠lno given 2 draw oe as a perpendicular bisector to ln by construction 3 ∠leo ≅ ∠neo transitive property of equality 4 m∠leo = 90° definition of a perpendicular bisector 5 m∠neo = 90° definition of a perpendicular bisector 6 le ≅ en definition of a perpendicular bisector 7 δole ≅ δone side-angle-side (sas) postulate 8 ol ≅ on cpctc nina made two errors in the proof. identify and correct the errors.

Sarah needs 3 feet of fabric for a project she is working on, but the store only sells the fabric in meters. one meter of fabric costs $1.20. how much will the fabric cost?

Write an expression that is equivalent to ( 3+14)+27.
