Concept explainers
To find: the measurement of the given numbered angle.
Answer to Problem 34E
Explanation of Solution
Given:
Concept used:
If a triangle is a right triangle, so both acute angles are complementary.
Sum of the three angles of triangle is always
Vertical opposite angles are always equal.
If the triangle is right triangle then other two angles other than
Calculation:
The given triangle is a right triangle, so both acute angles are complementary.
Angle
This mean that:
Since, vertical opposite angle are always equal.
Two angles are said to be complementary when sum of the two angles is
Two angles are said to supplementary when sum of the two angle is
Hence,
