To trisect an angle you first construct an equilateral triangle?
Right
What is the measure of the third angle of the triangle?
The third angle of a triangle is equal to 180 degrees minus (the sum of the first two angles).
How many degrees does a triangle third angle have?
it depends on the first two: angle3 = 180 - angle1 - angle2
In a triangle the measure of the first angle is 24 degrees more than the measure of the second angle. The measure of the third angle is four times the measure of the second angle. If the total number?
Let the second angle be x degrees. The first angle would then be x + 24 degrees, and the third angle would be 4x degrees. According to the triangle angle sum theorem, the sum of all three angles in a triangle is 180 degrees. Therefore, you can set up the equation x + (x + 24) + 4x = 180 and solve for x to find the measures of all three angles.
In a triangle the second angle is twice the first angle and the third angle is 20 less than the first angle find the measure of all three angles?
Remember the sum of the 3 angles of a triangle = 180degrees Let angle 1 = x angle 2 = 2x angle 3 = x-20 Sum = x + 2x + x - 20 =180o 4x - 20 = 180o 4x = 200o x = 50o 2x = 100 o x - 20 = 30o angle 1 = 50o angle 2 = 100 o angle 3 = 30o
