Step-by-step explanation:
a a reflex angle is more than 180° but less than 360° so in this case the reference angle of 95 degrees we are going to take 360° - 95 degrees to get255°
Only 2 forces are out of balance - the 22N and the 14N
So the resultant force is 22-14 = 8N.
Answer:
B.
Vertical angles are the same angles of each other.
14 + 7 = 21
3(14) - 21 = 21
Answer:
π = C / d
Step-by-step explanation:
The circumference of a circle is given by the general formula;
C = 2 * π * r .... or C = π d (r = radius, d = diameter)
We can easily modify the second formula to isolate π in order to express the circumference in relation to the diameter:
π = C / d
To obtain π, you need to divide the circumference by the diameter.
We're used to think about the circumference in terms of radius... but since we deal with 2 * r * π and that 2 * r = d... it's also convenient to use the diameter.
