A figure consists of four angles. The angle measures are as follows: m∠1=65° , m∠2=90° , m∠3=30° , and m∠4=25° . Which two angles are complementary angles? Identify by the angle number and not the degree measurement. List the smaller angle value first and the larger angle value second.(1 point)
Two angles are considered complementary if their sum is equal to 90 degrees.
In this figure, the angles with measurements 65° (angle 1) and 25° (angle 4) are complementary since 65° + 25° = 90°.
One of two complementary nonadjacent angles has a measure of 43°. What is the other angle measure?(1 point)
°
If two angles are complementary, their sum is 90 degrees.
Let's call the measure of the first angle 43 degrees.
To find the measure of the other angle, we can subtract the measure of the first angle from 90 degrees:
90° - 43° = 47°
Therefore, the measure of the other angle is 47°.
