Answer:

103°

Step-by-step explanation:

∠CEA and ∠DEB are vertically opposite angles same as ∠CED and ∠AEB.

Vertically opposite angles are angles that form when two lines intersect

From the figure given, lines CB and AD intersect to form vertically opposite angles mentioned above. Vertically opposite angles are equal, meaning

∠CEA=∠DEB and ∠CED=∠AEB

Replacing ∠CED=∠AEB, we get

(14x+7)°=(12x+17)°

Solve for x

(14x-12x)=17-7

2x=10

x=10÷2=5

value for x in ∠CED=∠AEB, we get (14×5)+7=77°

To calculate ∠CEA and ∠DEB

Let ∠CEA=∠DEB=y

∠DEA=180°since its a straight line therefor

(14x+7)°+y=180°

77+y=180

y=∠CEA=∠DEB=103°

A number has the digits 2, 8 and 6 to the nearest ten the number rounds to 830. what is the number. Please break it down.

Assoli18 [71]

The number would be 826. 826 rounded to the nearest ten would be 830 because when you have a number at the end that is 5 or higher, it would round up.

Angle A B D is a right angle, which is the measure of Angle C B D? Angle A B D is intersected by line C to form angles 75 degree

drek231 [11]

Answer:

15 degrees

Step-by-step explanation:

Since ABD is a right angle it equals 90 degrees

ABC is 75 degrees

ABC + CBD = ABD

75 + CDB = 90

Subtract 75 from each side

75-75 + CDB = 90-75

CDB = 15

The other angle is 15 degrees

Find the velocity, v(t), for an object moving along the x-axis if the acceleration, a(t), is a(t) = 3t^2 + cos(t) and v(0) = 2.

Scorpion4ik [409]

$\bf \displaystyle a(t)=3t^2+cos(t)\implies \stackrel{velocity}{\int~ [3t^2+cos(t)]dt}\\\\\\ t^3+sin(t)+C=~~~v(t)
\\\\\\
\begin{cases}
v(0)=2\\
v=2\\
t=0
\end{cases}\implies 0^3+sin(0)+C=2\implies C=2
\\\\\\
\boxed{t^3+sin(t)+2=v(t)}$

A first number plus twice a second number is 9. Twice the first number plus the second totals 27. Find the numbers

SOVA2 [1]

Create a a system of 2 equations: 2x + y = 27 and 2y + x = 9, with x being the first number and y being the second. solve for the two variables and you'll get the first number is 15 and the second is -3.
