Answer:

46 and 88° or 67 and 67°

Explanation:

An isosceles triangle has two sides of equal length and one other of a different length;

A triangle with such features also has 2 equal angles and one other;

If we consider that 46° is the angle that is not one of the two equal ones, then we can calculate the other two;

All angles in a triangle sum to 180, so:

180 - 46 = 134

The two remaining angles constitute 134° collectively;

If they are equal, each angle can be found like so:

¹³⁴/₂ = 67

Each of the two equal angles will be 67°;

Alternatively, if 46° is one of the two equal angles, then these two angles will be:
46 × 2 = 92

Then, the remaining angle can be found like so:

180 - 92 = 88

So the angles within the triangle are either:

46, 46 and 88°

or

46, 67 and 67°

Use the balanced equation of a nitrogen cycle pathway below to support the conservation of matter and energy.
Nastasia [14]

Law of thermodynamics states that matter and energy cannot be destroyed or created, but can be converted from one form to another. A balanced equation ensures that this basic principle is observed.

On the left-hand side of the equation (the reactants), there are 2 Nitrogen moles and 8 Hydrogen moles. After the reaction, the molecules are rearranged. Nonetheless, the moles of Nitrogen and Hydrogen in the products remain the same.

What use are the descending branches of glacial plants to them?​
kupik [55]

Answer:

Explanation:

A glacier forms where the accumulation of snow exceeds its ablation over many years, often centuries. Glaciers slowly deform and flow under stresses induced by their weight, creating crevasses, seracs, and other distinguishing features. They also abrade rock and debris from their substrate to create landforms such as cirques, moraines, or fjords. Glaciers form only on land and are distinct from the much thinner sea ice and lake ice that forms on the surface of bodies of water.

Describe what messages are sent by the nervous system when you go outside wearing a sweater on a very hot day.​
mr_godi [17]

Answer and Explanation:

In homeostatic control processes any deviation from the norm sets into motion the appropriate corrective mechanisms which restore the norm. This rectification occurs through negative feedback. When you go outside wearing a sweater on a hot day, the body sends messages to the CNS and the following occurs:

  • The superficial blood vessels vasodilate so that more blood flows near the surface. This encourages heat loss.
  • Sweating and panting. Sweat secreted by the sweat glands evaporate from the surface of the body as it absorbs latent heat.
  • The metabolic rate falls so that the body generates less heat. You also become less active
  • Behavioural response by seeking cooler areas, cold drinks or removal of the sweater.

What does each phase of mitosis look like
Sphinxa [80]
Interphase: You could not distinguish any parts of the cell.
Prophase: You could clearly see the chromosomes throughout the cell.
Metaphase: The chromosomes where lines up in the middle of the cell.
Anaphase: You could see the chromosomes were separated to ether side of the cell.
Telophase: The entire cell was separated to each side but was not split into its own cell.
Cytokinesis: In this step the cell had totally separated and there was now two separate daughter cells.
