Special cases of the sum and difference formulas for sine and cosine yields what is known as the double‐angle identities and the half‐angle identities.
Answer:
{e}, {m}, {w}, {e,m}, {e,w}, {m,w}, {e,m,w}
Answer:
Draw intersecting arcs inside the angle from points D and E without changing the compass width.
Step-by-step explanation:
The next step from here, will be :
Draw intersecting arcs inside the angle from points D and E without changing the compass width.
After this, draw a straight line from B to the arcs made from above step. This line is the angle bisector.
Answer:
The answer is 170
Step-by-step explanation:
Because 8 + 9 = 17, if we multiply all of these values by ten or add a zero to the end of each number, we should get
80 + 90 = 170
