Answer:

A = 73.33

B = 53.33

C = 53.33

Step-by-step explanation:

Since they are in a triangle, the sum of the three angles = 180

A + B + C = 180 ••••••(i)

Since B and C are congruent, it means that they are equal;

hence B = C ••••••(ii)

We can rewrite equation i as;

A + B + B = 180

A + 2B = 180 ••••••(iii)

Lastly;

B = A -20 •••••(iv)

Substitute iv into iii

A + 2(A -20) = 180

A + 2A -40 = 180

3A = 180 + 40

3A = 220

A = 220/3 = 73.33

But B = C = A -20 = 73.33 -20 = 53.33

An earth satellite remains in orbit at a distance of 11550 km from the center of the earth. what speed would it have to maintain
marishachu [46]
<span>11,550 km has to be changed to 11,550,000 meters

G · m · t² = 4 · π² · r³  we can change that to
</span>t² = (4 · π² · r³) / <span>(G · m )
t^2 = 4*PI^2*r^3 / (G*m)
</span>t^2 = 4*PI^2*<span>(11,550,000)^3 / 6.67*10^-11*5.98*10^24kg
t^2 = </span> <span> <span> <span> 6.083*10^22 </span> </span> </span> <span><span> </span> </span> / <span> <span> <span> 3.9</span></span></span>9 * 10^14
t^2 =  <span> <span> <span> 152,500,000</span></span></span>
t = <span>12,350 seconds
</span>and its orbital distance it travels is 11,550 * 2*PI = 70,050 kilometers

Therefore, it is traveling at 70,050 km / 12,350 second which equals
5.67 km per second which  <em>is 5,670 meters per second.</em>

HELP
soldier1979 [14.2K]

Answer:

Step-by-step explanation:

m∠5 +m∠6 = 180° ( the angles form a line)

m∠2 + m∠3 = m∠6 ( exterior angle is the sum of 2 not adjacent angles)

m∠2+m∠3+m∠5= 180° (sum of angles in a triangle is 180°)

Answer:

\boxed{D. 3 {x}^{2}  - x - 6}

Given:

f(x) =  3{x}^{2}  - 4 \\  \\ g(x) = x +  2

To Find:

(f - g)(x) = f(x) - g(x)

Step-by-step explanation:
