What is the missing step in the given proof? a. ∠pqc and ∠acp are supplementary by the linear pair theorem. b. for parallel lines cut by a transversal, corresponding angles are congruent, so ∠acb ≅ ∠pcq. c. ∠ocp ≅ ∠bcd by the vertical angles theorem. d. for parallel lines cut by a transversal, corresponding angles are congruent, so ∠ocp ≅ ∠abc. e. for parallel lines cut by a transversal, corresponding angles are congruent, so ∠oca ≅ ∠cbd.

Grace is standing 18 feet from a lighthouse and kelly is standing 10 feet from grace. the angle that grace looks up to see the top of the lighthouse is 45°. the angle that kelly looks up to see the top of the lighthouse is y°. find the height, h, of the lighthouse. find the angle, rounded to the nearest tenth of a degree, in which kelly looks up to the top of the lighthouse. to the nearest tenth of a degree, find the value of x° . in two or more sentences, explain your calculations
