Answer:
40°
Step-by-step explanation:
We can find the tangent of ∠J using the trigonometrical ratios which may be expressed in the form SOA CAH TOA Where,
SOA stands for
Sin Ф = opposite side/hypotenuses side
Cosine Ф = adjacent side/hypotenuses side
Tangent Ф = opposite side/adjacent side
The hypotenuse is the side facing the right angle while the opposite is the side facing the given angle.
Considering triangle ΔJKL, where ∠L=90°, JK = 7.3 feet, and KL = 4.7 feet
As such, with respect to angle J, JK is the hypotenuse, KL is the opposite side
Hence
Sin J = 4.7/7.3
Sin J = 0.643835616
J = 40.08°
Answer:
Pfffft only one. I went to California
Step-by-step explanation:
Answer:
z = -2
Step-by-step explanation:
7z + 4 - 9z = 8 (The first step is to combine like terms, so 7z -9z = -2z)
-2z + 4 = 8 (Subtract 4 on each side)
-2z = 4 (Divide each side by -2)
z = -2
You can plug -2 back in to check, and you get:
7(-2) + 4 -9(-2) = 8
-14 + 4 + 18 = 8
8 = 8
Hopefully, this helped. Good luck!
