The polar coordinate system and the rectangular coordinate system are
both designed to label points in the plane. They differ in the ways
they represent points in the plane.
Step-by-step explanation:
14 < 6×?
6×3=18
therefore anything above 3 multiplied by 6 would be greater in value than 14
If two angles are supplementary, then they add up to 180.
Angle 1 = twenty less than four times the other angle
Angle 2 = the other angle
Angle 2 = 1x
Angle 1 = 4x - 20
Next, we can add up angles 1 and 2 and set the sum equal to 180.
x + 4x - 20 = 180
5x - 20 = 180
5x = 200
x = 40
Now that we know x, we can find the values of our angles.
Angle 1 = 4(40) - 20 = 160 - 20 = 140 degrees
Angle 2 = 40 degrees
Hope this helps!! :)
Answer:
9.33
Step-by-step explanation:
Find the diagram attached, to get the length of RT, we will use the pythagoras theorem as shown:
Hyp² = opp²+adj²
Hyp = 11
Adj = 6
Opposite = RT
Substitute into the formula
11² = opp²+6²
Opp² = 11²-6²
Opp² = 121-36
Opp² = 85
Opp = 9.22
Hence the measurel RT to nearest hundredth is 9.22
Take away m from both sides to get 15=2m-9 and add 9 to get 24=2m, next divide by 2 to get m=12
