If cos θ= 12 /13 and θ is located in the Quadrant I, find sin (2 θ ), cos(2 θ ), tan(2 θ )

Yakvenalex [24]

Answers: sin(2∅) = 120/169, cos(2∅) = 119/169, tan(2∅) = 120/119

<h3>What are trigonometric functions?</h3>

Trigonometric functions are used to establish the relationship between the sides and the angles of a right angle triangle.

Analysis:

If cos∅ = adjacent/hypotenuse = 12/13,

Then, opposite of the right angled triangle = $\sqrt{13^{2} - 12^{2} }$ = 5

sin∅ = 5/13, cos∅ = 12/13, tan∅ = 5/12

sin(2∅) = 2sin∅cos∅ = 2(5/13)(12/13) = 120/169

cos(2∅) = $cos^{2}$ ∅ - $sin^{2}$ ∅ = $(\frac{12}{13}) ^{2}$ - $(\frac{5}{13} )^{2}$ = 144/169 - 25/169 = 119/169

tan(2∅) = sin(2∅) / cos(2∅) = 120/169 ÷ 119/169 = 120/119

The points (4,7) and (r. – 5) lie on a line with slope – 3. Find the missing coordinate r

dusya [7]

Answer:

$r=\frac{14}{3}$

Step-by-step explanation:

Set up an equation and solve for r using the formula for slope:

$\frac{5-7}{r-4}=-3\\ \\-2=-3(r-4)\\\\-2=-3r+12\\\\-14=-3r\\\\\frac{14}{3}=r$
