Chapter 1, Problem 1CT

Find the complement and the supplement of 70°.

To determine

Find the complement and supplement of ${70}^o$.

Answer to Problem 1CT

The complement of ${70}^o$ is ${20}^o$ and supplement of ${70}^o$ is ${110}^o$.

Explanation of Solution

Given:

The given angle is ${70}^o$.

Formula used:

To find the complement of a given angle subtract the given angle from ${90}^o$, and to find the supplement of a given angle, subtract the given angle from ${180}^o$.

Calculation:

The complement of ${70}^o$ is ${90}^o-{70}^o={20}^o$.

The supplement of ${70}^o$ is ${180}^o-{110}^o={70}^o$

Therefore, the complement of ${70}^o$ is ${20}^o$ and supplement of ${70}^o$ is ${110}^o$.
