Answer:

No it is D.52

Step-by-step explanation:

The angle has to equal 180 degrees.

180-76=104

52 time 2 equals 104

104=104

Answer:

$\boxed {\tt D. \ x=52}$

Step-by-step explanation:

The 2 angles are 2x and 76. They are on a straight line together. Therefore they are supplementary and add to 180 degrees.

$2x+76=180$

Solve for x by isolating x on one side of the equation.

76 is added to 2x. The inverse of addition is subtraction. Subtract 76 from both sides of the equation.

$2x+76-76=180-76\\2x=180-76\\2x=104$

x is multiplied by 2. The inverse of multiplication is division. Divide both sides of the equation by 2.

$2x/2=104/2\\x=104/2\\x=52$

x is equal to 52 and D is the correct answer.

Write an equation of a line that passes through (3, -1) and is parallel and perpendicular to y = 6x - 4

Serhud [2]

Here,

y=mx+c

the slope of the line 6x+4y= -16 is -20.

if the two lines are perpendicular, the slope of 1st line * slope of second line=-1

the slope of the 2nd line is -1/2

y-y1=m(x-x1)

y-13=-1/2(x- -18)

when you solve, you get the equation of the line as 2y+x=50

In basic geometry, if two geometry objects intersect at right angles (90 degrees or π / 2 radians), they are vertical.

If two lines intersect at right angles, the line is perpendicular to another line. Explicitly (1) if two lines intersect, the first line is perpendicular to the second line. (2) At the intersection, the straight line angle on one side of the first line is cut by the second line into two congruent angles. Verticality can be shown as symmetric. That is, if the first line is perpendicular to the second line, then the second line is also perpendicular to the first line. Therefore, two straight lines can be said to be perpendicular (to each other) without specifying the order.

Harry, Peter and 7 girls sit in a row. Harry can't sit in an end seat. In how many ways can they be arranged?

Sonja [21]

All possibilities = 9!
possibilities that harry sits at an end = 8! + 8!
possibilities that harry doesn't sit at an end = 9! - 8! -8!
