Answer:
Step-by-step explanation:
720,080 in expanded form with components
(7 X 10>50
Answer:
Step-by-step explanation:
0.5cos(2pi/9x-7pi/9)-4.5
X is equal to 30 (vertically opposite angles)
y=180-50
=130 degrees (angles in a straight line equal to 180)
z=180-130-30 (angle sum of a triangle equal to 180)
z=20 degrees
The answer for part a would be 130
the answer for part b would be 60
