DBH make a triangle.

The three inside angles of a triangle need to equal 180

H = 180 - B - D

H = 180 - 39 - 36 = 105

H and X make a straight line that equals 180 degrees

X = 180 - H

X = 180 - 105 = 75 degrees.

Find the exact value of the trigonometric expression given that sin u = − 8 17 and cos v = − 24 25 . (Both u and v are in Quadra
Rashid [163]

Answer: sin u = -5/13 and cos v = -15/17

Step-by-step explanation:

The nice thing about trig, a little information goes a long way. That’s because there is a lot of geometry and structure in the subject. If I have sin u = opp/hyp, then I know opp is the opposite side from u, and the hypotenuse is hyp, and the adjacent side must fit the Pythagorean equation opp^2 + adj^2 = hyp^2.

So for u: (-5)^2 + adj^2 = 13^2, so with what you gave us (Quad 3),

==> adj of u = -12 therefore cos u = -12/13

Same argument for v: adj = -15,

opp^2 + (-15)^2 = 17^2 ==> opp = -8 therefore sin v = -8/17

The cosine rule for cos (u + v) = (cos u)(cos v) - (sin u)(sin v) and now we substitute: cos (u + v) = (-12/13)(-15/17) - (-5/13)(-8/17)

I am too lazy to do the remaining arithmetic, but I think we have created a way to approach all of the similar problems.

Michael pays $30 to enter a state fair, plus $4 for each ride. Which of the following
lawyer [7]

Answer:

The required equation is:

y=4x+30

So, Option C is correct option.

Step-by-step explanation:

Entry fee for fair = $30

Cost of one ride = $4

Cost of x rides = $4x

If y represents the total cost the equation will be sum, of entree fee and cost of x rides i.e

y=4x+30

The required equation is:

y=4x+30

So, Option C is correct option.

Hat is the surface area of a sphere with a diameter of 16 cm
Ludmilka [50]

The surface area of a sphere of radius r is A = 4π*r^3.

Since the radius in this case is 8 cm (half the 17 cm diameter), the area of this sphere is

A = 4π(8 cm)^2, or 256π cm^2.
