1) Find the measure of 0. (imagine that is an x) 2) Then, find the measure of AB. (the length from A to B) ​

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 )
