Answer:

About 65.86 degrees

Step-by-step explanation:

A supplementary angle means that the angles add to 180 degrees.

Angle E + Angle F = 180 degrees.

You can then plug in the given equations for E and F.

2x + 5 + 5x - 38 = 180

Combine like terms:

2x + 5x = 7x

5 - 38 = -33

New equation: 7x-33=180

Remove the -33 from the left side of the equation by adding 33 to each side

7x-33+33 = 180+33 ---> 7x = 213

Divide by 7 on each side

7x/7 = 213/7 ---> x = about 30.43

You can then plug this into your equation for E and solve

2(30.43) + 5 = 65.86 Degrees

Answer:

$x=12$

Step-by-step explanation:

First, note that the angles shown are vertical angles. In other words, the two equations are equivalent to each other.

Therefore, set the equations equal to each other and solve for x;

$6x+7=8x-17$

Add 17 to both sides:

$6x+24=8x$

Subtract 6x from both sides:

$24=2x$

Divide both sides by 2:

$x=12$

Therefore, the value of x is 12.

And we're done!

Step-by-step explanation:

$-----------------------------$

$Here's$ $how$ $we$ $solve$ $the$ equation

$-1.2\left(3-x\right)$ = $-1.8$

$-1.2\left(3-1.5\right)$ = $-1.8$

$-3.6+1.2\cdot1.5$ = $-1.8$

$1.2\cdot1.5$ = $-1.8$

What are the x-coordinates for the maximum points in the function f(x)=4cos(2x-pi) from x=0 to x=2pi?

wel

The maximum value attained by the function will be 4
4 = 4cos(2x - π)
cos(2x - π) = 1
2x - π = 0
x = (nπ)/2
From x = 0 to x = 2π, n = 1, 2, etc
The equation will yield +4 for odd values of n and -4 for even values of n
