In trigonometry, the trigonometric ratios are used to determine the value of the trigonometric functions of the angles of a right triangle.

The trigonometric ratios is commonly called SOH-CAH-TOA, according to the formulas used to obtain then.

Given a right triangle with angles A, B and C and sides 17, 8 and 15.

Since, the denominator of the given ratio is 15, which is not the hypothenuse (the slant side), thus, the trigonometric function is neither sin nor cos but tan, thus we look for the angle which the side of length 15 is the adjacent side. The required angle is B.

Therefore, 8/15 represent tan B.

How do I solve and what’s the answer to 6(4s+12)=8(3s-14)

Inessa05 [86]

Answer:

No solution

Step-by-step explanation:

If you distribute 6 and 8 through the parentheses you get

24s+72= 24s-112

Cancel equal terms on both sides of the equation.

72=-122

There are no values of s that make the equation true. No solution.

. Find sets of parametric equations and symmetric equations of the line through the point parallel to the given vector or line (

omeli [17]

Answer:

a) L(x,y,z) = (-4,0,2)+(2,8,-7)*t

b) (2-z)/7= y/8=(x+4)/2 (option B)

Step-by-step explanation:

the parametric equation of the line passing through the point P₀= (-4,0,2) and parallel to the vector v=2i + 8j - 7k is

L(x,y,z)=P₀+v*t

therefore

L(x,y,z) = (-4,0,2)+(2,8,-7)*t

x=x₀+vx*t = -4 + 2*t

y=y₀+vy*t = 8*t

z=z₀+vz*t = 2 -7*t

solving for t in the 3 equations we get the symmetric equation of the line:

(2-z)/7= y/8=(x+4)/2

thus the option B is correct

Solve the equation for x. Enter your answers as radical expressions. Then estimate to one decimal place, if necessary.

Darya [45]

Hope you won't be turned off by a correction, but we really need to use the symbol " ^ " to denote exponentiation.

Thus, we have x^2 = 100

Taking the square root of both sides, we get x = plus or minus 10. Verify, please, that both x = -10 and x = +10 satisfy the given equation.
