Mathematics
1 answer:

Answer:

I put it in step by step because it is easier. (ans)

Step-by-step explanation:

Angle 1: It is a right angle so it is (90 degrees).

Angle 2: A triangle has 180 degrees. 90 plus 22 is 112 and 180 minus 112 is (68 degrees).

Angle 3: Since angles 2 and 3 are supplementary (2 angles summed to 180 degrees), 180 minus 68 is (112 degrees).

Angle 4: This is the same angle as 3 so it is also (112 degrees).

Angle 5: This is supplementary to 3 and 4 so 180 minus 112 is (68 degrees).

Angle 6: There are markings meaning the side lengths are the same. The angle opposite of its lengths are corrosponding. So meaning unnamed angle and 6 are the same. So 180-68 is 112 and 112/2 is (56 degrees).

Angle 7: We already know the unnamed angle is 56 degrees as it is the same as angle 6. Unnamed angle and 7 are supplementary. 180 minus 56 is (124 degrees).

Angle 8: It is the same as angle 7 (124 degrees).

4b + 11 + 8b + 1 = 180
skelet666 [1.2K]

Answer:

b=14

Step-by-step explanation:

Add 4b and 8b, which you get 12b. Then you add 11 and 1 which you get 12.

12b + 12 = 180 is the next equation.

Afterwards, you subtract 12 from 180.

12b = 168

Divide 12b from 168.

b = 14

What are trigonometric relations?

Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles

The six trigonometric functions are sin , cos , tan , cosec , sec and cot

Let the angle be θ , such that

sin θ = opposite / hypotenuse

cos θ = adjacent / hypotenuse

tan θ = opposite / adjacent

tan θ = sin θ / cos θ

cosec θ = 1/sin θ

sec θ = 1/cos θ

cot θ = 1/tan θ

Given data ,

Let the triangles be ΔRST and ΔQRT

Now , from the figure

∠S = 90° in the triangle ΔRST

And RS = 2/√3

∠T = 60° in the triangle ΔRST

Now ,

sin 60° = opposite / hypotenuse

           = RS / RT

           = ( 2/√3 ) / RT

We know , sin 60° = √3 / 2

Substituting the value of  sin 60° in the equation , we get

√3 / 2 = ( 2 / √3 ) / RT

Multiply by RT on both sides , we get

RT x ( √3 / 2  ) =  ( 2 / √3 )

Divide by ( √3 / 2  ) on both sides , we get

RT = ( 2 / √3 ) x ( 2 / √3 )

RT = 4 / 3

Therefore , the value of RT = 4/3

Now , from the figure

∠R = 90° in the triangle ΔQRT

and ∠T = 45° in the triangle ΔQRT

So ,

tan 45° = opposite / adjacent

We know tan 45° = 1

Substituting the value for tan 45° = 1 in the equation , we get

1 = opposite / adjacent

1 = x / RT

Multiply by RT on both sides , we get

x = RT

So , x = 4/3

Hence , The value of x is 4/3

he yearbook club had a meeting. The meeting had 24 people, which is three-fourths of the club. How many people are in the club
WINSTONCH [101]

Answer:

32 people

Step-by-step explanation:

If 3/4 equals 24, we need to find the other fourth. We can divided the total number of people by the numerator. 24/8, then add 8, which equals 32.
