Answer: x - 3y = -2
x = -2 + 3y
x - 3y = 16
x = 16 + 3y
Answer:
m∠A = 45.86°
Step-by-step explanation:
A rough sketch of the triangle is shown in the attached pic.
When 3 sides are given and we want to solve for an angle, we use the Cosine Rule. Which is:
Where a, b, p are the lengths of 3 sides (with p being the side opposite of the angle we are solving for) and P is the angel we want to solve for
Thus, we have:

Answer:
y = 5
y = 2.2
Step-by-step explanation:
For the first one:
9x = 9 x1 = 9
9 - 6 = 3
3y = 15
15 ÷ 3 = 5
y = 5
For the second one:
6x = 6 x 1 = 6
6 + 21 = 27
27y = 60
60 ÷ 27 ~ 2.2
y = 2.2
Answer:
gravity, also called gravitation, in mechanics, the universal force of attraction acting between all matter. ... On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth's mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects.
