ab+xy−5
Step-by-step explanation:
yx+ab−5 = xy+ab+−5
Simplify-
ab+xy−5
Answer:
x ≈ 20.42, y ≈ 11.71
Step-by-step explanation:
Using the cosine ratio on the right triangle on the right, that is
cos20° =
= 
Multiply both sides by y
y × cos20° = 11 ( divide both sides by cos20° )
y =
≈ 11.71
Using the sine ratio on the right triangle on the left, that is
sin35° =
=
= 
Multiply both sides by x
x × sin35° = 11.71 ( divide both sides by sin35° )
x =
≈ 20.42
