How do I find the measure of angle ABE??

Mathematics
1 answer:

3 0

You find the measure of angle BEC, by adding angle B and angle C which is 43+90, and then subtract that from 180 and get 180-(43+90). Then you take the measure of angle BEC (which is the same as AEB), take AEB and A which is 90 degrees and add those together. Then you take that and subtract it from 180, which is 180-(AEB+90)

What is the answer to this?
Dmitry [639]

Answer:

  (c)  III

Step-by-step explanation:

If you simplify the equations and the left side is identical to the right side, then there are an infinite number of solutions: the equation is true for all values of x.

Another way to simplify the equation is to subtract the right side from both sides. If that simplifies to 0 = 0, then there are an infinite number of solutions.

__

<h3>I. </h3>

  2x -6 -6x = 2 -4x . . . . eliminate parentheses

  -4x -6 = -4x +2 . . . . no solutions (no value of x makes this true)

__

<h3>II.</h3>

  x +2 = 15x +10 +2x . . . . eliminate parentheses

  x +2 = 17x +10 . . . . one solution (x=-1/2)

__

<h3>III.</h3>

  4 +6x = 6x +4 . . . . eliminate parentheses

  6x +4 = 6x +4 . . . . infinite solutions

__

<h3>IV.</h3>

  6x +24 = 2x -4 . . . . eliminate parentheses; one solution (x=-7)

Math problem I need help giving brainlist
Liono4ka [1.6K]

Answer:

x = 28

Step-by-step explanation:

7(8 - x) = -5x

56 - 7x = -5x                 Distribute 7 to the parenthesis

56 = 2x                         Add -7x to both sides

28 = x                           Divide 2 to both sides

Which is the best first step when solving the following system of equations? x + y = 3. 4 x minus y = 7. Multiply the first equa
____ [38]

Answer:

just add the equation and solve it then the value of X could be found then put the value of X and the value of y can be found. Just like in the below

Step-by-step explanation:

X+y=3 ------------ equation 1

4x-y=7 ------------ equation 2

adding equation 1 and 2

X+y=3

+ 4x-y=7

-----------------

5x = 10

X = 10/5

X = 2

putting the value of X in equation 1

or, 2+y=3

or, y = 3-2

Thus, y = 1

Trigonometry that’s due in one hour :(
expeople1 [14]

Answer:

(a)  \theta=\tan^{-1}(-0.890)

\implies \theta=-41.66908262 \pm 180 \textdegree n

\implies \theta=138.3309174..., 318.3309174...

\implies \theta=138\textdegree, 318\textdegree

(b)  \theta=\cos^{-1}\left(\dfrac{\sqrt{3} }{2}\right)

\implies \theta=30 \textdegree \pm360 \textdegree n, 330 \textdegree \pm360 \textdegree n

\implies \theta=30 \textdegree , 330 \textdegree

(c)  \theta=\sin^{-1}\left(\dfrac{1 }{2}\right)

\implies \theta=30 \textdegree \pm360 \textdegree n, 150 \textdegree \pm360 \textdegree n

\implies \theta=30 \textdegree , 150 \textdegree
