Find the measure of the indicated angle.

Answer:

So If you start with sinØ = .5

your calculator is programmed to always give the closest angle to 0, and that would be 30°

You probably used the cosine law to find the first angle. A suggestion is to always find the largest angle first. If that happens to be an obtuse angle, your calculator will find the correct angle.

Of course there can only be one obtuse angle in a triangle, so using the sine law for your second angle does not result in any problems

notice that in your solution 78 and 102 add up to 180 , and sin 78 = sin(180-78) = sin 102

I would have found angle S first, the largest angle always opposite the largest side.

7^2 = 5^2 + 4^2 - 2(5)(4)cosØ

40cosØ = -8

cosØ = -8/40 = -1/5

Ø = 101.537°

Now you can use the sine law and you will find the correct other angles.

Answer: [tex]67.68^{\circ}[/tex]

Step-by-step explanation:

Given

[tex]\angle W=90^{\circ}[/tex]

[tex]VW=32\ ft[/tex]

[tex]WU=78\ ft[/tex]

from the figure, we can write

[tex]\Rightarrow \tan v=\dfrac{UW}{VW}\\\\\Rightarrow \tan v=\dfrac{78}{32}\\\\\Rightarrow \tan v=2.437\\\Rightarrow v=\tan^-1(2.437)\\\Rightarrow v=67.68^{\circ}[/tex]

Answer:

measure of angle 5 = 75 degrees

Step-by-step explanation:

given measure of angle 8 = 105 degrees,

angle 8 and angle 5 are in a linear pair so,

(the sum of angles in a linear pair is 180 degrees)

therefore, angle 8 + angle 5 = 180 degrees

therefore,. 105 + angle 5 = 180 degrees

angle 5 = 180 - 105

angle 5 = 75 degrees

Answer:

180 blue   70 red

Step-by-step explanation:

b= blue      r = red

b+r = 250

r = (250-b)

If 40% is removed the rest is 60%

If the 70% is removed the rest is 30%

0.6b + 0.3(250-b)  = 129

0.6b + 75 - 0.3b = 129

  0.3b = 54

divide by 0.3

  b = 180

    250-180 =  70

   60% 0f 180 = 108

   30% of 70 = 21

   108 +21 = 129

Answer:

28/53

Step-by-step explanation:

We need the cos of Q

therefore we'll use CAH (in SOH, CAH, TOA)

where CAH means

cos(angle)=adj/hyp

the side that adjacent to Q is 28

and the hypotonous (the oppsoite to the right angle) is 53

therefore cos(q)=28/53

= (2-1)/√6

=1/√6 or √6 /6

Answer:

15ways

Step-by-step explanation:

This question bothers combination

Combination has to do with selection

Given

Total number of teams  = 6

champion and runner up = 2

number of ways is expressed as 6C2

6C2 = 6!/(6-2)!2!

6C2 = 6!/4!2!

6C2 = 6*5*4!/4!*2

6c2 = 30/2

6C2 = 15

Hence the number of ways they can be selected is 15ways

Step-by-step explanation:

Area of a rectangle is l*w  l=12 and w=6: 12*6=70

Area of triange A is 1/2*b*h, b=3 and h=6: 1/2*3*6=9

Area of triangle B is 1/2*b*h, b=3 and h=6: 1/2*3*6=9

Area of parallelogram is Area of rectangle- Area of triangle A - Area of triangle B: 70-9-9=52
