Using the law of sines,
sin80°/3.1 = sin∠QSR/2.4
∠QSR = sin^-1(2.4sin80°/3.1)
≈ 49.679°
∠SQR = 180° - 80° - 49.679° (angles in a triangle)
= 50.321°
sin50.321°/RS = sin80°/3.1
RS = (3.1sin50.321°/sin80°)
= 2.4 units (nearest tenth)
The length of line RS is 2.4 units.
You are given the function of identity of cos(6x) = 2cos^2(3x)-1. <span>A sine and cosine function is one of the basic
functions encountered in Trigonometry. Sine is equal to the opposite side over
hypotenuse whereas the cosine function is equal to the adjacent side over the
hypotenuse.</span>
Answer:
6x^2+x+7
Step-by-step explanation:
(3x^2+3)+(3x^2+x+4)
6x^2+3+x+4
6x^2+x+7
The perimeter of any shape is just what you get when you add up all of the side lengths. We know that one side is 462 meters, and since a square has four equal sides, we can just mulitply 462 × 4 to get our perimeter, 1,848 meters.
Answer:
If you are finding the Area in which you would need for the carpet would be A= 232 ft
Step-by-step explanation:
A = lw
l = 16
w = 14.5
16 x 14.5 = 232 feet
