The origin is the centre of the axis, and has the coordinates (0,0). It is important because it is essentially the "origin" of the number on the axis.
Answer:
D=4
Step-by-step explanation:
X(8-4x)/3
Answer: 8x-4x^2/3
M∠A = x
m∠B = 3x+24
m∠C = x + 51
x + 3x+24 + x + 51 = 180
5x + 75 = 180
5x = 180 - 75
5x = 105
x = 105/5
x = 21
m∠A = x = 21°
m∠B = 3x+24 = 3*21 + 24 = 87°
m∠C = x + 51 = 21 + 51 = 72°
Answer:
Example
Step 1 The two sides we know are Adjacent (6,750) and Hypotenuse (8,100).
Step 2 SOHCAHTOA tells us we must use Cosine.
Step 3 Calculate Adjacent / Hypotenuse = 6,750/8,100 = 0.8333.
Step 4 Find the angle from your calculator using cos-1 of 0.8333:
