Capitolo 2, Problema 1
Give the measures of the complement and the supplement of an angle measuring 35° .
Guida verificata passo dopo passo1
Recall the definitions: The complement of an angle is what, when added to the angle, equals 90°, and the supplement of an angle is what, when added to the angle, equals 180°.
To find the complement of the given angle (35°), set up the equation: \(\text{complement} + 35^\circ = 90^\circ\).
Solve for the complement by subtracting 35° from 90°: \(\text{complement} = 90^\circ - 35^\circ\).
To find the supplement of the given angle (35°), set up the equation: \(\text{supplement} + 35^\circ = 180^\circ\).
Solve for the supplement by subtracting 35° from 180°: \(\text{supplement} = 180^\circ - 35^\circ\).

Complementary Angles
Complementary angles are two angles whose measures add up to 90 degrees. To find the complement of a given angle, subtract its measure from 90°. For example, the complement of a 35° angle is 90° - 35° = 55°.

Supplementary Angles
Supplementary angles are two angles whose measures add up to 180 degrees. To find the supplement of a given angle, subtract its measure from 180°. For instance, the supplement of a 35° angle is 180° - 35° = 145°.
