In a triangle, one of the angles is 43 degrees, and the angle adjacent to the other internal angle is 102 degrees. Find the larger corner of the triangle. Give your answer in degrees.
The angle adjacent to the internal angle is 102 °, we find the value of this angle:
180 ° – 102 ° = 78 °.
Find the third corner of the triangle: 180 ° – (43 ° + 78 °) = 59 °.
The angles of the triangle are 43 °, 59 °, and 78 °.
Answer: The larger angle of the triangle is 78 °.
