Expert Solution & Answer
Answer to Problem 2CT
Angles of triangle are 15°, 45° and 120°. It is an obtuse angled triangle.
Explanation of Solution
Given information:
Ratio of angles of the triangle are 1:3:8.
Formula used:
Sum of angles of triangle is 180°, that is,
Calculation:
Let the common multiple of the angles be “
Therefore, according to the given ration now the angles will be
Now substituting the values of angles in the sum of angles equation,
Cross multiplying the values,
The values of angles is
Hence, the angles of the triangle are 15°, 45°, and 120°
The triangle is an obtuse angled triangle, because one of the angles in the triangle is an obtuse angle.
