Answer:
a) adjacent angles, complementary angles
b) vertical angles, congruent angles
c) supplementary angles, adjacent angles
d) supplementary angles, adjacent angles
Step-by-step explanation:
Adjacent angles are angles that share a common vertex, ( usually angles that are right next to each other )
Complementary angles are angles that form a 90 degree angle ( right angle )
Supplementary angles are angles that form a straight line
Vertical angles are angles that are vertically aligned with each other ( vertical angles are congruent )
Divide 166.47 by 17.9 to get w by itself. The width of the rectangle is 9.3 units.
Answer:
68:76.5
Step-by-step explanation:
create the ratio 68/x=8/9, then simplify the side you can so get 68/x=.8888... then multiply both sides by x to get rid of the fraction, 68=.8888...x. now divide both sides by .8888... to get x by itself, 76.5=x

3y + 11 + 7x - 30 + 5x + 14
3y + 12x - 5
3y = -12x + 5
y = (-12x + 5)/3
x = (3y - 5)/-12
hope this helps
