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.
A function--namely a parabola (concave up). To "evaluate" this function you would need an x value and would find the resulting y value. To "solve" this function, you would probably be given a y value and asked to find the corresponding x value(s).
Replace a value for x, then solve for y, to find the corresponding value for y. Repeat for other values of x.
Supplementary angles add up to 180 degrees. So, if x is the supplementary angle to 148.7 degrees, solve for x: 148.7+x=180 x=180-148.7=31.3 degrees
Complementary angles sum to 90°. Supplementary angles sum to 180°. Given an angle x then the complement of x is 90 - x, and the supplement of x is 180 - x.
Supplementary angles are angles that add together to equal 180, which is different from complementary angles that equal 90. So 180-37=143.
Suppose the angle is x, Then its supplementary is 180-x So x+39 = 2(180-x) = 360-2x Then 3x = 399 So x = 133 and 180-x = 47
The measures of two angles in a triangle are shown in the diagram. Which equation can be used to find the value of x?
Supplementary angles add up to 180 degrees
Suppose the angle is x then the second is 5x. The two angles are supplementary so x + 5x = 180 or 6x = 180 so that x = 30 degrees.
Supplementary angles are angles which add to 180o. So, one angle is nine times as large as the other, therefore letting the smaller angle be X, we have the following: 9X + X = 180 10X = 180 X=18o and the other is 9 times this amount or 162o
Angles are supplementary if they add up to 180. So, with some algebra 45+x=180 x=180-45=135
supplementary angles are angles that have a sum of 180*.another way to remember that its 180* is the two p's in the word make 8.example. 70*+110*= 180* supplementary.Complementary angles add up to 90 degrees.Supplementary angles are two angles whose sum add up to 180 degrees. Can be shown as (180 - x)
An angle and the angle that it is supplementary to have a total measure of 180 degrees.Let x be the supplementary angle. 4x would be the original angle.x + 4x = 1805x = 180x = 364x = 144So the two angles are 144 degrees and 36 degrees.
If it is a scalene triangle then: 180 - the sum of the 2 known angles = x angle
