Use the fact that the sum of all three angles in a triangle is 180 degrees.
25 degrees
As the third angle must be 42 degrees, it is a scalene triangle.
The sum of angles in a triangle is always 180 degrees. Since two angles are each 35 degrees, the third angle would be 180 - (35 + 35) = 180 - 70 = 110 degrees.
110
It is an obtuse triangle
35 and 110 degrees (180 degrees in a triangle)
As the third angle must be 42 degrees, it is a scalene triangle.
The sum of angles in a triangle is always 180 degrees. Since two angles are each 35 degrees, the third angle would be 180 - (35 + 35) = 180 - 70 = 110 degrees.
The 3rd angle is: 180-55-80 = 45 degrees
An obtuse triangle will have an angle of 110 degrees with 2 different acute angles that all add up to 180 degrees.
all angles of a triangles add to 180 degrees.180 - 110 - 35 = 35 is your answer
a scalene triangle
110
110180 - (2 x 35) = 110
Exterior angle of any plane figure total 360 degrees, so 360 - (110 + 100) ie 360 - 210 = 150
It is an obtuse triangle
35 and 110 degrees (180 degrees in a triangle)
The 3 angles of a triangle always add up to 180 degrees. You have 110 and 43, so that is 153 degrees. Subtract 153 from 180, and that is the remaining angle.
