Answer:
19 degrees
Step-by-step explanation:
Sum of 2 angles is complementary,
x + 71 = 90
x = 90 - 71
x = 19 degrees
Answer:
6000π m²/h
Step-by-step explanation:
Area of the circular cloud =πr²----------------------------------------- (1)
Radius as a function of time = R(t)=50+20t------------------------ (2)
dA/dt = (dA/dr) x (dr/dt)-----------------------------------------------------(3)
dA/dr = 2πr
dr/dt = 20
After 5 hours, the radius of the cloud will be :
R(5)=50+20(5)
= 150 meters
Substituting into (3)
dA/dt = 2π(150) x 20
= 6000π m²/h
Answer:
x = 22
Step-by-step explanation:
triangle = 180 degrees
2x + 12 + x + 54 + 3x - 18 = 180 degrees
combine like terms
6x + 12 + 54 - 18 = 180
6x + 48 = 180
<u> -48 -48</u>
6x = 132
divide by 6
x = 22
