The lowest common multiple of 6 and 9 is 18

18/6 = 3....she needs 3 packs of cards
18/9 = 2...she needs 2 packs of envelopes

so by buying 3 packs of cards and 2 packs of envelopes, she will have 18 of each

A jet leaves Reno, Nevada and is headed toward Miami, Florida at a bearing of 100°. The distance between the two cities is appro
Likurg_2 [28]
So hmm, if you notice the picture below

"y" would be the opposite to the 10° angle, and "x" would its adjacent

Reno is "y" north and "x" west from Miami

\bf sin(\theta)=\cfrac{opposite}{hypotenuse}\implies sin(10^o)=\cfrac{y}{2472}  solve for "y", to see how much north

and \bf cos(\theta)=\cfrac{adjacent}{hypotenuse}\implies cos(10^o)=\cfrac{x}{2472}  solve for "x" to see how much west

make sure, that in both cases, your calculator is in Degree mode, since the angle is in degrees, as opposed to Radian mode


now... for the section B)

if notice the Reno-Miami line, and you were to draw a North line through it, anywhere in between, or at an endpoint like the in the picture at Reno, the "clockwise" angle, will always be the same, 100°

bear in mind ( no pun intended ), that Bearings use the North line, and the clockwise angle from it, as in the picture below

IgorLugansk [536]

Answer:

The wide is 70.02 m.

Step-by-step explanation:

First you need to draw a triangle with only one 90 degrees angle.

The opposite side to the 90 degrees angle will be the hypotenuse.

We will call the remaining sides ''Baseline'' and ''River wide''.

The angle between hypotenuse and baseline is 35 degrees.

The triangle has one 90 degrees angle so we can apply the tangent equation

in the angles that are no 90 degrees.

Tangent (angle) = Opposite side/adjacent

Tan(35°)= River wide/100m

River wide = 100m.Tan(35°)

River wide = 70.02 m
