Answer:

arrow 4

Step-by-step explanation:

The amount of energy needed in the transformation from liquid to gas is equal to the gas to liquid transition.

Boiling is the mechanism by which a substance passes from the liquid phase to the gaseous form.

Like water diagram in phase:

Evaporisation is a method of phase shift in which the water transitions from a liquid to a gas (water vapour).

Condensation is the process of phase shift in which water transitions from a gas to a liquid, and the vapour becomes a cloud.

Which is the height of the triangle?<br> ( PIC IS PROVIDE PLS HELP ME)

zysi [14]

<h3>Answer: 80 meters</h3>

This is an isosceles triangle. The dashed line is the height which is perpendicular to the base 120. The height is always perpendicular to the base. The dashed line cuts the base into two equal pieces (this only works for isosceles triangles when you cut at the vertex like this).

So we have two smaller triangles each with a base of 60 and a height of x. Focus on one of the right triangles and use the pythagorean theorem to solve for x.

a^2 + b^2 = c^2

x^2 + (60)^2 = (100)^2

x^2 + 3600 = 10000

x^2 = 10000 - 3600

x^2 = 6400

x = sqrt(6400)

x = 80

Each smaller right triangle has side lengths of 60, 80, 100

Note the ratio 60:80:100 reduces to 3:4:5. A 3-4-5 right triangle is a very common pythagorean primitive.
