How do you find the value of x for a triangle?
It all depends on which aspect of the triangle you are being asked to find and what values you already have. If you wish to find an angle, certain values must already be known and you can use trigonometry to find X. If you are asked to find the length of a side, Pythagoras can be used if the triangle contains a right angle. Remember, the angles inside a triangle always add up to 180 no matter what, so if you have two angles and simply wish to find the third, all you need to do is find the remaining difference.
How do you find out the value of x on a parallelogram?
A parallelogram has 2 sets of equal sides.That means that there are 2 sets of the same angles.If one angle is 100 degrees,the angle diagonal of it is also 100 degrees.So as long as you know one angle you can calculate the rest since all the angles have to add up to 360 degrees.So if there are three unknown angles but one is 100 degrees.One of the unknown angles is also 100 degrees.And since that equals to 200 degrees,minus 360 by 200 and you get 160 which is the combined degrees of the last two angles which are the same.So the last two angles are both 80 degrees.
Can you add 3x plus 1?
You cannot add 3x and 1. You can add 3x and x and get 4x though.
What number must you add to complete the square x2 plus 12x equals 40?
You must add 36 to complete the square on the left hand side.You must add 36 to complete the square on the left hand side.You must add 36 to complete the square on the left hand side.You must add 36 to complete the square on the left hand side.
What number must you add to complete the square x2 plus 2x equals -1?
You must add 1

Do the sum of the interior angles of a triangle always equal 180 degrees?
Yes the 3 interior angles of any triangle always add up to 180 degrees
The interior angles of a triangle always add up to what?
180 degrees.
What do the angles of an obtuse-angled triangle add up to?
The 3 interior angles of any triangle will always add up to 180 degrees
What do the interior angles of a triangle add up to and what do the exterior angles add up to?
The interior angles of a triangle add up to 180 degrees. The exterior angles of a triangle add up to 360 degrees.
What does a triangle measure to?
The 3 interior angles of any triangle always add up to 180 degrees
How many total degrees does a triangle have?
The interior angles of a triangle always add up to 180 degrees.
What is a interior angle?
Interior angles are angles on a triangle that add up to 180
What relationship exists regarding the angles in a triangle?
The interior angles of a triangle always add up to 180°Because the interior angles always add to 180°, every angle must be less than 180°The bisectors of the three interior angles meet at a point, called the incenter, which is the center of the incircle of the triangle.Note The interior angles only add to 180° when the triangle is planar, meaning it is lying on a flat plane. If the triangle is not planar, for example if it is lying on the curved surface of a sphere, the angles do not add to 180°.
