Step-by-step explanation: If the measure of the larger of the two complementary angles is 38 more than three times the measure of the smaller angle.
This tells us there are two angles.
A larger one
A smaller one
We then look for which angle is being compared to the other one.
"38 more than three times the measure of the smaller angle"
This tells us the smaller angle is the angle that being compared to thus it can be labeled as x.
Let x = the smaller angle
To find the larger angle we must write out all the modifications. This angle is 38 more than. To represent 38 more than we can say +38 (more than indicating addition).
To represent three times the angle we can write 3x (three copies of x)
Thus...
Let 3x+38 = the larger angle.
If both angles are complementary then they add to 90 so..
Identity Property of Multiplication Definition. This property is also known as the multiplication property of 1. It states that the result of multiplying any real number by 1 is the number itself.
