A triangle with two congruent sides and an angle of 104 degrees is?

A triangle with two congruent sides is isosceles. A triangle with an angle of 104 degrees is obtuse. So you would have an obtuse isosceles triangle.

What type of angle is 104 angle?

An angle that is 104 degrees would be considered an "Obtuse" angle. This is because the degrees in the angle are over 90.


Which angle measures 104 degrees?

An angle of 104 degrees is an obtuse angle because it is greater than 90 but less than 180 degrees

What are the other two angles and its 3rd side of a triangle with one angle of 104 degrees with two sides of 31 cm by 42 cm?

Let the sides of the triangle be abc and their opposite angles be ABC:- 3rd side: c^2 = 31^2 +42^2 -2*31*42*cosine(104) = 3354.964616 sq rt = 57.9 Using cosine rule angle B: (31^2+57.9^2 -42^2)/(2*31*57.9) = 44.7 degrees Angle A: 180 -104 - 44.7 = 31.3 degrees So the two angles are 44.7 degrees and 31.3 degrees with the 3rd side being 57.9 cm


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.


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
