Complementary angles = 90°
x= angle 1
(90-x)= angle 2
Subtract the two angles to get the difference between them (18°).
(90-x) - x= 18
combine like terms
90 - 2x= 18
subtract 90 from both sides
-2x= -72
divide both sides by -2
x= 36° angle 1
Substitute answer in to find angle 2:
=90 - x
=90 - 36
=54° angle 2
Hope this helps! :)
GCF: greatest common factor
4 is the biggest number that goes into both 8 and 20 so that is the GCF
Answer:
C, 150 in
Step-by-step explanation:
12 in x 25 = 300
300/2
=150 in
This would be displayed as 11 - 5k
This cannot be solved, however, without knowing the value of k, or at least what the expression is equal to.
