Answer:

m∠C = 72°

BA = 8.6

AC = 2.8

Step-by-step explanation:

We can start by finding the sum of all angles in a triangle to find angle C. The sum of all angles is 180°, so we can write the equation:

m∠A + m∠B + m∠C = 180°

And substitute what we have:

90° + 18° + m∠C = 180°

108° + m∠C = 180°

m∠C = 72°

In order to find the side BA, we can use trig functions. We are given the hypotenuse and we are looking for the side adjacent to ∠B. The trig function that relates the two is cosine. We can set up the equation as follows:

cos(∠B) = [tex]\frac{BA}{BC}[/tex]

cos(18°) = [tex]\frac{BA}{9}[/tex]

9 * cos(18°) = BA

BA ≈ 8.559508647

And when we round, we get:

BA = 8.6

In order to find the side AC, we can use trig functions. We are given the hypotenuse and we are looking for the side opposite to ∠B. The trig function that relates the two is sine. We can set up the equation as follows:

sin(∠B) = [tex]\frac{AC}{BC}[/tex]

sin(18°) = [tex]\frac{AC}{9}[/tex]

9 * sin(18°) = AC

AC ≈ 2.781152949

We can round this to:

AC = 2.8

Answer:

24/25

Step-by-step explanation:

COS = adjacent/hypotenuse

Answer:

24/25

Step-by-step explanation:

my answer is 24/25

Answer:

The sum of the angles in a triangle is 180°, so the angles do form a triangle. Since two of the three angles are congruent, the triangle is an isosceles triangle. An infinite number of isosceles triangles exist with different side lengths. Therefore, more than one triangle exists with the given angle measures.

Answer:

Area of ¼th part of circle =¼πr²=¼×3.14×12²

=113.04in²

Area of rectangle ABCD=l×b=8×17=136in²

Area of rectangle DEFG=l×b=5×3=15in²

Total area : 113.04+136+15=264.04 =264 square inches.

Answer:

area = 263.04 in²

Step-by-step explanation:

area = (8 x 17) + (5 x 3) = (0.25 x 3.14 x 12²) = 135 + 15 + 113.04 =263.04 in²

Answer:

6 5/8

you want to solve the whole numbers and fraction parts sepreatly then combine.

Answer:

53/8

Step-by-step explanation:

[tex]16\frac{7}{8} -10\frac{1}{4}[/tex]

convert to improper fractions

[tex]\frac{7+16*8}{8} -\frac{1+10*4}{4}=\frac{135}{8} -\frac{41}{4}[/tex]

the common denominator is 8, so multiply the second fraction by [tex]\frac{2}{2}[/tex].

[tex]\frac{135}{8} -\frac{41*2}{4*2}=\frac{135}{8} -\frac{82}{8}[/tex]

subtract

[tex]\frac{135}{8} -\frac{82}{8}=\frac{135-82}{8}=\frac{53}{8}[/tex]

Answer:

396 mm squared

Step-by-step explanation:

(8 x 12) ÷ 2 = 48

48 x 2 = 96

10 x 10 = 100

100 x 3 = 300

300 + 96 = 396

Answer:

78°

Step-by-step explanation:

when two lines intersect it creates 4 seperate angles, here it gives us 78°, and we know that the angle across from it is the same, so they equal.

Answer:

60

Step-by-step explanation:

The outside of the circle will measure 360 all of our known values are added up to equal 240 so subtract it from 360 to get 120

Now divide 120 by half to get 60 since the outside is double the size of the inside

Hope this helps

Answer:

60

Step-by-step explanation:

Angle R is an inscribed angle so it is 1/2 of TS. Since a circle is 360 degrees, we find TS by subtracting (90 + 150) from 360 which gives us TS = 120.

x = 1/2(120) = 60 degrees

Answer: [tex]9\pi\ in.[/tex]

Step-by-step explanation:

Given

The diameter of a circle is [tex]d=9\ in.[/tex]

So, the radius is [tex]r=\frac{d}{2}=4.5\ in.[/tex]

The circumference is given by [tex]2\pi r[/tex]

Insert the values

[tex]\Rightarrow 2\pi \cdot 4.5\\\Rightarrow 9\pi \ in.[/tex]

Thus, the circumference of the circle is [tex]9\pi\ in.[/tex]

Complete question :

En France, en 1900, la taille moyenne des femmes était de 1,54 m et celle des hommes de 1,66 m. Entre

1900 et 2010 ces tailles moyennes ont augmentées d'environ 5,55%.

Calculer, en mètres, l'arrondi au centième des tailles moyennes des femmes et des hommes en 2010.​

Répondre :

Femmes = 1,63

Hommes = 1,75 m

Explication étape par étape:

Étant donné que :

Taille moyenne en 1900:

Hommes = 1,66 m

Femmes = 1,54 m

Pourcentage d'augmentation de poids d'ici 2010 = 5,55%

1 + 5,55% = 1 + 0,0555 = 1,0555

D'où,

Taille des femmes en 2010:

1,0555 * 1,54 = 1,62547 = 1,63 m

Pour la taille des hommes en 2010:

1,0555 * 1,66 m = 1,75213 = 1,75 m
