The value of Sin(a) suppose that Cos B = 0.68 in which case, a + B = 90° is; 0.68.

<h3>Trigonometry</h3>

First, when we have two angles, whose sum equals, 90°.

In essence, Since the algebraic sum of angles A and B is 90°;

  • A + B = 90.

  • B = 90 -A.

By trigonometric identity;

  • Sin A = Cos (90 - A)

Where; (90 - A) = B.

Therefore; Sin A = Cos B = 0.68.

babunello [35]

Answer:

r^{3}=4050

r = ∛4050

Step-by-step explanation:

V=\frac{4}{3} \pi r^{3}

5400=\frac{4}{3} \pi r^{3}

r^{3}=3(\frac{5400}{4} )

r^{3}=3(1350 )

r^{3}=4050

Determine the measurement of the unknown angle measures in the given figure.
Andrei [34K]

Answer:

To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.

trig problem a dog walks 3.5 miles southeast then 8.2 miles north of east what is the resultant vector
WITCHER [35]

Answer:

8.9miles

Step-by-step explanation:

Kindly find attached a rough sketch of the dog's movement.

Step one:

given data:

let the movement southeast be x,=3.5miles

and let the movement northeast be y=8.2 miles

let the resultant be z

Step two:

The resultant vector can be found using the Pythagoras theorem

z^2=x^2+y^2

z=√x^2+y^2

substituting we have

z=√3.5^2+8.2^2

z=√12.25+67.24

z=√79.49

z=8.9miles
