Two angles with measures os (2x + 7) and (3x + 3) are complementary. Find x
2x+7+3x+3=90
5x+10=90
5x=90-10=80
5x=80
x=80/5
x=16
The complement of 38° is:
x+32=90
x=90-32=52
)If an acute angle measures (80 - 3x)°, find its complement.
y+(80 - 3x)°=90
y=90-(80 - 3x)°
y=10+3x
Find the Perimeter of a regular octagon whose side measures 5 in
5x8=40
