Given:

$\angle a$ and $\angle b$ are complementary angles.

$\angle a=32^\circ$

To find:

The measure of $\angle b$ .

Solution:

According to the definition of the complimentary angles, the sum of two complementary angles is always 90 degree.

It is given that, $\angle a$ and $\angle b$ are complementary angles. So,

$\angle a+\angle b=90^\circ$

$32^\circ+\angle b=90^\circ$

$\angle b=90^\circ-32^\circ$

$\angle b=58^\circ$

Therefore, the measure of $\angle b$ is 58°.

Sergio039 [100]

Answer: 41 or 85

<u>Step-by-step explanation:</u>

Range is the difference between the largest number and the smallest number.

The largest number is 72. 72 - 31 = 41

The smallest number is 54. 54 + 31 = 85

Adding either ONE of those numbers will result in a range of 31.
