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

In a right triangle the acute angles measure x plus 15 and 2x degrees. What is the measure of the larger acute angle of the triangle?
The 3 interior angles of a right angle triangle add up to 180 degrees and so:- If: x+15+2x+90 = 180 Then: 3x = 75 and so x = 25 Therefore the largest acute angle is 2x = 50 degrees Check: 45+55+90 = 180 degrees
Triangle PQR has angles in the ratio of 2 35 . which type of triangle is PQR?
The sum of the angles in a triangle is 180. Since the ratio of the angles is 2:3:5 their measurements are 2x, 3x, and 5x. When you add them together you will get 180. So... 2x+3x+5x=180 10x+180 x=18 Since x=18 the measure of the angles are 2x=36 3x=54 5x=90 Since one of the angles is 90 we know that the triangle is a RIGHT triangle.
What type of triangle is a equals A equals x B equals 2x and C equals 4x?
Assuming A, B and C are angles, it is an obtuse angled triangle.
The obtuse angle of an isosceles triangle measures 120 degrees write and solve an equation to find the measure of the base angles?
Well if it has 180 degrees over all, and the two base angles have to be congruent, then the equation is 180-120=2x or each base angle is 30 degrees.
Line BC has an equation of a line y 2x plus 3 and line EF has an equation of a line y negative one over 2x plus 4. These two equations represent (5 points)?
If you mean y = 2x+3 and y = -1/2x+4 then the two lines are perpendicular to each other meeting at right angles.

So... 2x+3x+5x=180 10x+180 x=18 Since x=18 the measure of the angles are 2x=36 3x=54 5x=90 Since one of the angles is 90 we know that the triangle is a RIGHT triangle.
Angles of isoceles triangle?
The interior angles of a triangle add up to 180. So a triangle with 3 equal sides (or angles) will have 60-degree angles. * * * * * True, but the question is about an isosceles triangle, not an equilateral triangle. The angles of an isosceles triangle are x, x and 180-2x degree where x is a measure between 0 and 90 degrees.
What degrees are each corner in an isosceles triangle?
The sum of the interior angles of a triangle is 180o. In an isosceles triangle two of the angles are the same, say x. The third angle is then 180o-2x.
What is the value of x if one side of the triangle is 133 and the other is 2x and the other is x plus 20?
Without seeing a diagram of the triangle and any possible angles: 153 > x > 372/3 There will be no triangle if the sum of the two shorter sides is less than or equal to the length of the longest side. This occurs if: 2x + (x+ 20) ≤ 133 ⇒ x ≤ 372/3 or if: 2x ≥ (x+ 20) + 133 ⇒ x ≥ 153
Angles X and Y are supplementary If the measure of angle X equals 2x plus 4 and the measure of angle Y equals 4x plus 20 then what is the measure of each angle and why?
X = 180 - Y so 180 - Y = 2x + 4 and Y = 4x + 20 so 180 - 4x - 20 = 2x + 4 therefore 6x = 156 so x = 26 making Angle X = 56o and Angle Y = 124o
What type of triangle is a equals A equals x B equals 2x and C equals 4x?
Assuming A, B and C are angles, it is an obtuse angled triangle.
The middle angle in a triangle measures 1 degree more than 2 times the smallest angle and 53 degrees less than the largest angle Find the measure of angles of the triangle?
middle angle= 51 degrees smallest angle= 25 degrees largest angle= 104 degrees x=25 ; y=104 I can't really show you how I got the answer but I suggest you draw a picture and then it's much easier to figure out. We don't need a figure to compute the measure of the angles, since we know that the sum of the measure of angles in a triangle is 180 degrees. Let x be the smallest angle, so the middle angle is 1 + 2x, and the larger angle is 53 + 1 + 2x or 54 + 2x. Then we have: x + (1 + 2x) + (54 + 2x) = 180 5x + 55 = 180 5x + 55 - 55 = 180 - 55 5x = 125 5x ÷ 5 = 125 ÷ 5 x = 25 1 + 2x = 1 + 2(25) = 51 54 + 2x = 54 + 2(25) = 104
How do you find the value of x in a rhombus with measure of 2x plus 5 and 2x plus 1?
I see that your given information is about the angles of the rhombus. Then, 2x + 5 + 2x + 1 = 180 combine like terms on the left side 4x + 6 = 180 subtract 6 to both sides 4x = 174 divide by 4 both sides, then simplify the result x = 87/2 degrees.
The obtuse angle of an isosceles triangle measures 120 degrees write and solve an equation to find the measure of the base angles?
Well if it has 180 degrees over all, and the two base angles have to be congruent, then the equation is 180-120=2x or each base angle is 30 degrees.
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 perimeter of a triangle 7x plus 9w 2x plus 8y 2y plus 5w?
The perimeter of a triangle is the sum of the lengths of the three sides.If the three expressions in the question are in fact the lengths of thethree sides, then the perimeter is their sum.(7x + 9w) + (2x + 8y) + (2y + 5w) = 9x + 10y + 14w
