1) Find the measure of 0. (imagine that is an x) 2) Then, find the measure of AB. (the length from A to B)
1 answer:
Answer:
θ ≈ 50°, AB ≈ 15.6
Step-by-step explanation:
Using the tangent ratio in the right triangle
tanθ = =
=
= 1.19 , then
θ = (1.19 ) ≈ 50° ( to the nearest degree
-----------------------------------------------------------------
Using the cosine ratio in the right triangle
cos50° = =
=
( multiply both sides by AB )
AB × cos50° = 10 ( divide both sides by cos50° )
AB = ≈ 15.6 ( to 1 dec. place )
