Answer to Problem 14PT
The triangle is a right angle triangle.The measure of the unknown triangle is
Explanation of Solution
Given:
Calculation:
The sum of measure of all three angles of a triangle is equal to
In the question, the measure of given angles is
Thus,
Thus, the measure of the unknown triangle is
Clearly none of the angles are equal to each other but one angle is right angle and hence the triangle is a right angle triangle.
Conclusion:
Therefore, the triangle is a right angle triangleand the measure of the unknown triangle is
