Name an angle bisector shown in the figure. DE AB GB CF

expeople1 [14]

Answer:

Step-by-step explanation:

we know that

An angle bisector is a line that divide an angle into two equal angles.

In this problem

$m\angle ACF=m\angle FCD$ ---> given problem

$m\angle ACD=m\angle ACF+m\angle FCD$ ---> by addition angle postulate

CF is an angle bisector of angle $m\angle ACD$

Answer:

x = - $\frac{3}{11}$

Step-by-step explanation:

Given

$\frac{x}{3}$ - $\frac{3-2x}{6}$ = $\frac{5}{2}$ x

Multiply through by 6 to clear the fractions

2x - (3 - 2x) = 15x ← distribute and simplify left side

2x - 3 + 2x = 15x

4x - 3 = 15x ( subtract 4x from both sides )

- 3 = 11x ( divide both sides by 11 )

- $\frac{3}{11}$ = x

What is the solution of this system of linear equations? 3y = 3x+6 27- 1x=3

Ludmilka [50]

3y=3x+6
/3 /3
y=x+2

27-1x=3
+1x +1x
27=3+1x
-3 -3
24=1x
/1 /1
24=x

y=x+2
y=24+2
y=26

the solution is 26

Two planes, A and B, start from the same place and move in different directions, making an angle of 50º between them. The speed

cluponka [151]

Answer: The distance between them is 230.65 miles.

Step-by-step explanation:

Since we have given that

Speed of plane A (b) = 200 miles per hour

Speed of plane B (c) = 300 miles per hour

Angle between them = 50°

So,

We will use the "Cosine formula", we get

$a^2=b^2+c^2-2bc\cos A\\\\a^2=200^2+300^2-2\times 200\times 300\cos 50\textdegree\\\\a^2=40000+90000-120000\cos 50\textdegree\\\\a^2=130000-120000\times 0.64\\\\a^2=130000-76800\\\\a^2=53200\\\\a=\sqrt{53200}\\\\a=230.65\ miles\ per\ hour$

So, distance between the two planes after one hour will be

$Distance=\frac{Speed}{time}=\frac{230.65}{1}=230.65\ miles$

So, the distance between them is 230.65 miles.
