Answer:
this figure is straight line angle is 180°.
angle rps+ angle qpr= angle qps
6x+11°+7x+143°=180°
13x+154°=180°
13x=180°-154°
13x=26
x=26/13
x=2
angle rps is 6x+11
6×2+11
23°
Answer:
Θ = 21.72°, 158.28°
Step-by-step explanation:
Given
sinΘ = 0.37
Since sinΘ > 0 then Θ is in first/ second quadrant
Θ = (0.37) ≈ 21.72°
Θ = 180° - 21.72° = 158.28°
Answer:he will use 45 minutes to burn 540 calories . he spend a total of 50 minutes ie including 5 minutes of rest.
Step-by-step explanation: 1 minute burns 12 calories
Therefore 540÷12 = 45 minutes plus 5 minutes of rest = 50 minutes.
An ice cream machine produced 44 ice cream per minute.
Now, after reconditioning it speeds up to 55 ice cream per minute.
=> 55 - 44 = 11
=> 11 / 44 = 0.25
=> 0.25 * 100% = 25%.
thus it increased it production to 25%.
You'll get (3n-2m)(3n-2m)
your final answer distributing or the by using the foil method will be 4m^2-12mn+9n^2
