3x plus 2x-20 equals 180?
3x + 2x - 20 = 180 5x - 20 = 180 Add 20 to both sides: 5x = 200 Divide both sides by 5: x = 40
Can the measures of an acute triangle be x x-1 and 2x?
No. Since x + (x-1) + 2x = 180 degrees ie 4x - 1 = 180 degrees, if follows that 2x > 90 degrees. So the largest angle is obtuse.
What is 2x square time 2x square?
(2x)2 times (2x)2 = 16x4 (2x2) times (2x2) = 4x4
What is 2x times -2x?

What is the measure of angle whos supplement is three times its compliment?
180 - x = 3(90 -x) 180 - x = 270 - 3x 3x - x = 270 - 180 2x = 90 x = 45 The angle is 45 degrees (complement is 45, supplement is 135).
What is 2x 11 62180?
what is 2x + 9 + 62 =180
The largest angle of a triangle is 6 times the smallest angle and 3 times the other angle Find the measure of the smallest angle?
x + 2x = 6x = 180 9x = 180 9x/9 = 180/9 x = 20....theres you answer
What is 2x plus 15 plus 2x equals 180?
First of all add all common factors. In par. (2x) + 15 + (2x) = 180 4x + 15 = 180 Divide 4x and 180 by 4. (4x/4) + 15 = (180/4) x + 15 = 45 Then subtract 15 to 15 and 45. x + (15-15) = (45-15) x = 30 Answer is X = 30.
If the measure of one angle is 3x and the measure of its complement is 2x what is the vale of x?
Complementary angles equals 180 degrees. If 3X + 2X = 180, then 5X = 180 so X=36 degrees.
What is the measure of an exterior angle for a 2x-gon?
360/2x = 180/x
Why is 2x cubed different from 2x times 2x times 2x?
2X * 2X * 2X = 8X^3 2X^3 is saying 2*( X * X * X) = 2X^3
What is 180 equals 11x plus 9x?
180=11x+9x. 180 = 20x. 18=2x. 9=x.
3x plus 2x-20 equals 180?
3x + 2x - 20 = 180 5x - 20 = 180 Add 20 to both sides: 5x = 200 Divide both sides by 5: x = 40
2x plus 3x plus 2x plus 3x equals 180?
Ok so 2x + 3x + 2x + 3x = 180.... so combine like terms, 2x + 3x + 2x + 3x is 10x, because 2+3+2+3 is equal to 10, and then so 10x = 180, so divide each side by 10 because the "10" on the left side is multiplying the x, and we want "x" by itself and the opposite of multiplication is division, and 10x/10 is x and 180/10 is 18, so x = 18.
Can the measures of an acute triangle be x x-1 and 2x?
No. Since x + (x-1) + 2x = 180 degrees ie 4x - 1 = 180 degrees, if follows that 2x > 90 degrees. So the largest angle is obtuse.
If the angles of a triangle measure 2x 2x and x plus 30 then the triangle is?
X=30 2x+2x+x+30=180; All of the angles in a triangle always add up to 180. Therefore 5x+30=180; subtract 30 to be 5x by itself. Therefore 5x=150; divide by 5 to find x. Therefore X=30 2(30)+2(30)+30+30=180
What is 2x square time 2x square?
(2x)2 times (2x)2 = 16x4 (2x2) times (2x2) = 4x4
