In ΔCDE, \overline{CE}

abruzzese [7]

Answer:

$m\angle CDE=14^o$

Step-by-step explanation:

we know that

An exterior angle of a triangle is equal to the sum of the opposite interior angles.

see the attached figure to better understand the problem

∠DEF=∠ECD+∠CDE

substitute the given values

$(4x+5)^o=(x+9)^o+(x+8)^o$

solve for x

Combine like terms

$(4x+5)^o=(2x+17)^o$

Group terms

$4x-2x=17-5$

$2x=12$

$x=6$

Find the measure of angle CDE

$m\angle CDE=(x+8)^o$

substitute the value of x

$m\angle CDE=(6+8)=14^o$

Y = 3000x + 28000
y = 2800x + 30000

3000x + 28000 = 2800x + 30000
200x = 2000
x = 10

The salaries will be the same after 10 years.

The measure of angle θ is 600°. The point (x, y) corresponding to θ on the unit circle is ______.

eduard

A unit circle has a radius of 1.

Θ = 600°

1 circle = 360°

Θ = 360° + 240°

(x,y) = cos 360° , sin 240°
(x,y) = -0.50 , -0.886

If these were the given choices:
<span>A.) -(3^(1/2))/2 B.)-1(2^(1/2))/2 C.)-1/2 D.) (3^(1/2))/2
</span>
x = C) - 1/2
y = A) -(3^1/2) / 2
