Answer: -240 = -4π / 3, 60 = π / 3, 270 = 3π / 2, 945 = 21π / 4, -30 = -π / 60, 195 = 13π / 12
Step-by-step explanation:
The formula for converting <em>Degrees </em>into <em>Radians </em>is <em>Degrees </em>* (π / 180) = <em>Radians</em>.
For -240, we have -240 * (π / 180) = -240π / 180 and simplifying gives us -4π / 3
60: 60 * (π / 180) = 60π / 180 = π/3
270: 270 * (π / 180) = 270π / 180 = 3π / 2
945: 945 * (π / 180) = 945π / 180 = 21π / 4
-30: -30 * (π / 180) = -30π / 180 = π / 60
195: 195 * (π / 180) = 195π / 180 = 13π / 12
The answer is 2.6 m/s
The speed (v) is distance (d) through time (t).
v = d/t
We know:
d = 390 m
t = 150 s
v = d/t
v = 390 m / 150s
v = = 2.6 m/s
Answer:
Step-by-step explanation:
Answer:
y=131°
x=53°
Step-by-step explanation:
∠ ABD and ∠ BDC are supplementary.
The sum of the supplementary angles =180 °
thus y-4+x=180...........i
x and 37° are complementary, that is, they add up to 90°
Thus, x=90-37=53°
Using this value in equation 1 we obtain:
y-4°+53° =180°
y= 180°-53°+4°
y=131°
