Since the sum of the measures of the angles of a triangle is 180 degrees, then:
3x + 4x + 5x = 180
12x = 180
x = 15
3x = 3 x 15 = 45
4x = 4 x 15 = 60
5x = 5 x 15 = 75
Thus the angles of the triangle are 45, 60, and 75 degrees.

If two angles of a triangle each measure 54 What is the measure of the third angle?
If two angles of a triangle each measure 55 what is the measure of the third angle?
The shortest side of a triangle is always opposite the angle with the measure?
angle with smallest measure - apex
If two angles of a triangle each measure what is the measure of the third angle?
180- total of the first two angles= 3rd angle
If the largest angle of an isosceles triangle measures 106 find the measure of the smallest angle?
The smallest angle would be = 38 degrees. Proof: Base angles of an isosceles triangle must equ All angles of the triangle must add up to 180 degress considering that the known angle is not under 89 degrees the other two must equal, yet both add up to 76 degrees.
What is the measure of base angle if vertex angle of an isosceles triangle is 80?
The base angles will have equal angles of 50 degrees
In a certain triangle the two smallest angles have the same measure The measure of the largest angle is twice the measure of the smaller angels what is the measure of the largest angle?
90o. Let A be the size of the smallest angle. Then the three angles are A, A & 2A. The sum of the angles in a triangle is 180o, thus: A + A + 2A = 180o 4A = 180o A = 45o So the largest angle is 2A = 2 x 45o = 90o.
If the measure of one angle of a triangle is 10 degrees more than the smallest angle The Measure of the third angle is 50 degrees more than the smallest Find the three angles?
The three angles are 40, 50 and 90 degrees.
Relations among the angles of a triangle?
In a triangle, the sum of the angles is always 180 degrees. This is known as the angle sum property of triangles. Additionally, the largest angle in a triangle is always opposite the longest side, and the smallest angle is opposite the shortest side.
