How do you solve for x using trig?
1 answer:
Step-by-step explanation:
in trig there are three functions: sin, cosine, and tan
when using trig, you are supposed to pick one angle to make the equation according to
sin= opposite ÷ hypotenuse
cosine= adjacent ÷ hypotenuse
tan= opposite ÷ adjacent
For example 13:
make the equation according to angle 41
you have the adjacent side and opposite side, so use the tan function
tan(41) =
move x so that it becomes a numerator by multiplying both sides by x:
(x) tan(41) = 4
divide both sides by sin(41): x = 4 ÷ tan(41)
plug this into your calculator to get 4.6

<u>Answer</u>:
the length of chicken coop and the garden is of 40 feet.
<u>Explanation</u>:
Given that the garden is the length of the chicken coop, equal length
→ 3x + 12 = 6x – 16
→ 3x - 6x = -16 - 12
→ -3x = -28
→
→
→ x = 9.33 feet.
- The garden length = 3(
) + 12 → 40 feet
- the chick coop length should be same as the garden length.
