Answer:
c = 70°
Step-by-step explanation:
The sum of the angles of a triangle is always 180°.
We can use the other two to solve for c:
57 + 53 + c = 180
110 + c = 180
c = 70
Therefore, angle c is 70°.
Answer:
third side =√{30²+16²)=34
sin theta/2=16/34
theta/2=sin-¹(16/34)
theta=28.07×2=56.14

Step-by-step explanation:
lmk if this is correct !
3x^2+6x^2-4x-8 = 3x^2(x + 2) - 2(x + 2) = (x + 2)( 3x^2 - 2) = 3(x+2)(x -
)(x +
)
The potential energy is converted into kinetic energy.
Therefore, for conservation of energy we have:
mgh = (1/2) m * v ^ 2
From here we clear the speed:
v = root (2 * g * h)
The height will then be:
h = v ^ 2 / (2 * g)
Substituting the values:
h = (34) ^ 2 / (2 * (32))
h = 18.0625 feet
Answer: The pear before it fell was 18.0625 feet up in the tree.
