Parallel lines<span> are coplanar </span>lines<span> that do not intersect</span>
Answer:
60
Step-by-step explanation:
<C+<D = 180 since they form a straight line
5x+20 +3x = 180
8x+20 = 180
Subtract 20 from each side
8x+20-20 = 180-20
8x = 160
Divide by 8
8x/8 = 160/8
x = 20
We want to find angle D
<D = 3x= 3*20 = 60
The answer is 1,500. You have to multiply 30 and 50.
2 to the 3rd power (2^3) times x to the second (x^2)
