The 3 interior angles of a right angle triangle add up to 180 degrees and so:- If: x+15+2x+90 = 180 Then: 3x = 75 and so x = 25 Therefore the largest acute angle is 2x = 50 degrees Check: 45+55+90 = 180 degrees
4140Improved Answer:-Exterior angles = 360 degreesInterior angles = 4140 degrees
There are (25-2)*180 = 4140 degrees
Scalene
If the two expressions given for the vertex angle are to be the same number, 6x + 8 = 9x -25; then 3x = 25 + 8 = 33 and x = 11. Therefore, the vertex angle is 6(11) + 8 = 74. The two base angles of an isosceles triangle must be the same and the three angles of the triangle must sum to 180. Therefore, calling the unknown base angle y, 2y + 74 = 180, or y equals 53.
It is an obtuse scalene triangle.
Yes
Yes. The general rule for angles is that the sum of the angles must be 180 degrees.
no. the angles in a triangle must add up to 180 degrees. The right triangles must have an right angle (90 degrees). If you add up all the angles they will not measure 180 degrees.
35 degrees because the 3 angles of a triangle add up to 180 degrees
a triangle has 180º so 180-90-25= 65
An obtuse triangle
To find the third angle of a triangle when two angles are known, you can use the fact that the sum of all three angles in a triangle is always 180 degrees. Therefore, if two angles are 45 degrees and 110 degrees, you can add these together to find the sum of the two known angles (45 + 110 = 155 degrees). Then, subtract this sum from 180 degrees to find the measure of the third angle: 180 - 155 = 25 degrees. Thus, the third angle of the triangle is 25 degrees.
Those triangles with 25 and 90 degree angles are called right angle triangle.
360
Because the total sum of interior angles of a triangle is 180 degrees.
Yes, a triangle has a total of 180 degrees of its angles. Since a right triangle has one angle that is 90 degrees, the other two angles much add up to 180-90=90 degrees. 65+25=90.
