AB =
Round your answer to the nearest hundredth.
5
C
А
65°
B

Step-by-step explanation:

Reference angle = 65°

Opposite side = 5

Hypotenuse = AB = ?

To find AB, the trigonometric ratio we would use will be:

Plug in the values

Cross multiply

Divide both sides by sin(65)

(nearest hundredth)

5 x 14?

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
