Question:
Recall that two angles are complementary if the sum of their measures is 90degrees. Find the measures of two complementary angles if one angle is 6 degrees more than two times the other angle?
Answer:
The angles are: 28 and 62 degrees respectively
Step-by-step explanation:
Let the two angles be x and y where the bigger angle is x.
So, we have:
[tex]x + y = 90[/tex] ---- Complementary angles
[tex]x = 6 + 2y[/tex] --- Given
Required
Find x and y
Substitute [tex]x = 6 + 2y[/tex] in the first equation
[tex]x + y = 90[/tex]
[tex]6 + 2y +y= 90[/tex]
[tex]6 + 3y= 90[/tex]
Solve for 3y
[tex]3y= 90 -6[/tex]
[tex]3y= 84[/tex]
Solve for y
[tex]y= 84/3[/tex]
[tex]y= 28[/tex]
Recall that: [tex]x = 6 + 2y[/tex]
[tex]x = 6 + 2 * 28[/tex]
[tex]x = 6 + 56[/tex]
[tex]x = 62[/tex]
So, the angles are: 28 and 62 degrees respectively
